Description: 1890? Two monochrome hidden-picture trade cards advertising "Incroyable de Paris" stitched shoes for women and men. 4⅜ x 3". Paris: Imp. F. Hermet. $14 from Bertrand Cocq, Calonne Ricouart, France, Sept., '18.

TH and "The Old Man and the Ass." I think I have found the hidden picture in these; click on the separate link-opener to see it resolved. At first I thought these were most likely stock trade cards, but reflection on the fact that the advertisement takes the complete verso and two parts of the front of either card, I decided that they more a particular creation of Incroyable de Paris. Incroyable offers very inexpensive stitched shoes. Might these contrast with wooden shoes?
