РОССIЯ. | UNION POSTALE UNIVERSELLE RUSSIE. | ОТКРЫТОЕ ПИСЬМО. — CARTE POSTALE. || On the reverse, a blue ink woodcut image is printed in the upper left corner, and a идгу штл inscription is in the bottom centre. Holding the postcard against the backlight reveals a hidden image of an indecent nature (erotic). The use of Latin characters "R" and "N" instead of Russian "Р"  and "Н" suggests that the cards were produced in Europe, probably in France. Inscriptions: 1. ПЕRВЫЕ ДNИ; 2. ПОRА ЛЮБВИ; 3. ВЪ ЛЮДИ; 4.
