These are antique pages from a French serial story called "Cartouche". We cannot find a date on these, but would guess that they are over 100 years old.
Each one is a separate little booklet with a black and white engraving on the front, and then 8 pages (or 4 double-sided pages) of the story in French. 7.25 by 11 inches. They are worn around the edges.
You get 1 piece.
