Iron tsuba of oval form with a shakudō fukurin and rough surface decorated by low relief carving and brass inlay with a centipede emerging from under the rock on both sides.
Edo period.Size: 78.9 x 73.6 x 3.8 mm
Unsigned. However, this tsuba may be (though with reservation) attributed to Misumi Kōji school. There is some information regarding this master(s) in Tsuba. An aesthetic study by Kazutaro Torigoye and Robert E. Haynes (from the Tsuba Geijutsu-kō of Kazataro Torigoye. Edited and published by Alan L. Harvie for the Nothern California Japanese Sword Club, 1994-1997) on pages 163-4, though I was not able to locate the tsuba in the original publication. Possibly, this fragment of the book was added by Robert Haynes. Markus Sesko speculates about Misumi in his The Japanese toso-kinko Schools.// Lulu Inc., 2012 on pages 374-5: "Misumi Kōjo Tsuba. Iron plate, elliptical shape, shakudō takabori suemon, yamagane fukurin. Centipede." But of course, visual similarity does not prove anything. I was not able to find any traces of signature or a triangle on the seppa-dai.

Reference to this design can be found in LIB-1359.2017 Japanese Swords and Tsuba from the Professor A. Z. Freeman and the Phyllis Sharpe Memorial collections, Sotheby's, London, Thursday 10 April 1997; p. 18-19, lot № 37: "A Kamakura-bori Tsuba, Momoyama Period. ...pierced with two large formalised butterflies..."
As Japanese Erotic Fantasies put it: "a couple engaged in love-making, their stare fixed outside the picture plane". This is the only image of series that has a reference in available western literature, and the only one found in museum collections: Rijksmuseum Amsterdam (RP-P-1999-2001-16); reference: Fukuda (ed.) (1990), pls. 11-2.
The scene of this print looks quite similar to that of the Kiyonaga's Sode no maki:
The woman is "a young lady-in-waiting of Shogun's Court or Daimyō's Mansion, enjoying a rare outing from her tedious chores" [Richard Lane]. She is fully dressed in her outer cloak (shikake), white paper hat (agebōshi or tsunokakushi), and toed socks (tabi). A book or maybe, onkotogami (roll of tissues known as 'paper for honourable act' ) is still in the folds of her kimono. She is holding an open fan, either to cover her and her lover's faces from an unsolicited witness or to bring some fresh air to their joined lips. The pair just started their sexual intercourse.
A scene from medieval times. A courtier in eboshi cap having sex with an aristocratic young woman with a long straight hairstyle (suihatsu).
Completely naked couple in the moment of ejaculation. Lavish garments with paulownia leaves on a yellow background counterbalance the white bodies on red bedding. The form of a woman's cheeks is telling, but I don't know about what. Maybe her advanced age?
The pose of the couple and the overall composition are similar to that of the previous sheet. Though the lovers are dressed, and the woman's hairdo is well kept. The male looks older and the woman - younger.
A man takes a young maid from behind. She clenches the sleeve of her kimono in her teeth; it's either the moment of penetration (beginning of intercourse) or of her orgasm (the end of it).
This seems to be a forced intercourse between a lackey with extensive bodily hair and a young maid from the same household.
This design is very much like the other one presented below, which is described at Japanese Erotic Fantasies on page 136 (pl. 43b) as follows: "The viewer peers through a mosquito net to see a child fast asleep, while his mother or wet-nurse moves towards her partner. On our print there is no child; instead of a sleeping baby, there is a roll of onkotogami. Fewer objects make the overall image concise, almost laconic in comparison with the Ehon hana fubuki (1802) design:
A young couple in a moment of true love. He is listening to the beating of her heart.
This is a moment of true love between an old monk and a young samurai. The latter even did not take of his socks (tabi).
From Japanese Erotic Fantasies: "Boats played a crucial role in the workings of Yoshiwara, as they were the primary means of transport to the district. During the hot summer months, trips on pleasure boats were also a favourite pastime. Sex aboard a boat is a recurrent theme in shunga".
The last print that I am currently lacking and hunting for:
I know where it is, but I cannot reach it... yet.

Data from 
Image from 
№1: "...one of the most exotic scenes in all shunga. A Dutch kapitan is discovered coupling with a lovely Japanese courtesan, beside a large window opening upon a garden...".
№2: "...a fair young harlot is seen masturbating with a grinding-pestle - a man watches intently from under bedding." [I have two specimens of this design; the one from album is more soiled but less faded].
№3: "...the artist has effectively contrasted the lovers by depicting the man's face as seen through the geisha's gauze skirt. [...] we are impressed more by strikingly elegant composition, the dramatic coloring, rather than feeling any great urge to participate in the energetic proceedings..."
№4: "This scene is a most straightforward one, featuring the standard Missionary Position [capitalization by R. Lane].; but withal, the contrast of the young and naked, secret lover and the richly-clothed courtesan amid luxurious bedding..."
№5: "In a striking lesbian scene (which has no equivalent in Utamaro, and is, incidentally, often omitted in later editions of this album), the girl at left prepares to receive the harikata (dildo) worn by the older girl at right (who holds a seashell containing lubricant)."
№6: "In the first appearance of a matronly heroine in this series, we find a widow - with shaven eyebrows and clipped hair - sporting with a handsome yound shop-clerk, mounting him with all her might."
№7: "... lady of samurai court: here, shown taking advantage of an official outing to temple and theatre, to rendezvous with a secret lover on a teahouse balcony." R. Lane considers this design the least successful in the series, especially in comparison with the same theme by Utamaro: "Utamaro female is almost ferocious in her lust for sexual gratification", which does not sound true to me. See Utamaro's sheet №5 from the album Utamakura (歌まくら, Poem of the Pillow) [courtesy The British Museum without permission]:
Then, as Richard Lane states, "we are flung suddenly to the bottom rung of Edo society":
№8: "Here we find a fair yotaka ('night-hawk', e.i. streetwalker) accommodating a lusty client in a lumberyard by the bank of the Sumida River".
№9: '... a slightly plump harlot of the lower class receives a night visit from her lover, whose naked form she tries to cover with a cloak."
№10: "...likely maidservant and lackey - are depicted in bath-room, their passions are all too obviously fired by steaming water."
№11: "...this scene of courtesan and secret lover ranks high not only in Eiri's œuvre but also in the annals of the ukiyo-e genre itself. Both design and colouring are impeccable and, for this period, there is nothing even in the work of great Utamaro that really surpasses it." Again, a doubtful statement, however, this is Utamaro's design for the reader to judge:
The last design in my album is this:
#13: In most reference books it goes under number 13, and we will assign this number to the sheet. "The final scene of the album features naked participants, probably samurai man and wife. The print is rather subdued in tone and colour, if not in the degree of the passion displayed..."
An additional sheet, acquired separately from a reputable dealer in New York, is usually listed as №12:
№12: "One might think that Eiri has reached his peak with the preceding plate 11 - and indeed he has, in both esthetic and erotic terms. But the album is not yet finished, and the next scene lends a needed variety to the series, a slightly comic tableau featuring a middle-aged lackey attempting to forcibly seduce a servant girl of the same domicile". Utamaro's design, that inspired Eiri is here:
All descriptions are taken from Richard Lane's article at The Complete Ukiyo-e Shunga №9 Eiri, 1996. He concluded: "...Eiri's erotic series represents a major contribution to shunga art towards the close of ukiyo-e "Golden Age". In part inspired by Utamaro's classic album, this series withal constitutes a unified and original achievement, providing a cumulative effect of gracefully elegant yet glowing eroticism, which remains in the mind's eye long after the pictures themselves are far away."
I only would like to mention here that in several reference sources this album goes under name of Eisho; unfortunately, this mistake is reproduced at
