Original educational board of shells

Illustrated educational board (these boards were published in Paris between the end of the 19th and the beginning of the 20th century. This is an original board and not a photocopy from an old one as we see many on Bristol. Dim approximately 24.5x37, 5 with the pass everywhere provided (large part of the enhancement of your image in the framing that you decide). Old document in very good condition for its age. Double-sided!.
