"Thérèse" was offered by a French seller user-75d14f4 on the online auction platform CATAWIKI in December 2021. The seller's description of this two-volume set was: "Re-edition, the date of which I was unable to determine. (London, no name, 1782) 2 duodecimo volumes of 115 and 77 pp., very lovely marbled sheepskin pastiche bindings, gilded triple fillets, adorned spines, black title labels. This classic of 18th-century clandestine erotica was written in 1748 by an author who has remained anonymous, attributed at the time to Montigny, which led to his internment in the Bastille. It is now attributed to the Jean-Baptiste de Boyer, Marquis d'Argens. Edition illustrated with 37 very unrestrained figures, engraved in intaglio after Borel, unsigned." I should have paid more attention to the first phase, about the re-edition, but I didn't. After a few bidding rounds, I won the book when the hammer price was 2,200 Euros. On the 28th of December, 2021, I paid for this little beauty $2,760. The book arrived a few days later.  The paper's quality and texture, the watermark, the absence of the platemark, and the lack of embossing on the back (text and plates) made me suspect it was a fake. The pages were absolutely flat to the touch!  I established clear evidence of a high-resolution 'xerox' copy using Celestron Micro Capture Pro micro-photography.  I wrote to the seller and the auction platform, explaining my doubts regarding its authenticity. To prove my point, I include a few micro photos of the "Thérèse" and some books printed at the end of the 18th century. I explained why I considered it a fake and requested a return/refund. After two months of email exchanges, the seller and the platform refused to pay me back. Today is the 2nd anniversary of the purchase. I still have the book. To celebrate my carelessness, I included it in my library to warn fellow book collectors about buying from an unknown dealer via certain online auction platforms. Ref.: Bamber Gascoigne.
