Chocolat Roval Monochrome Hidden Picture Cards · Carlson Fable Collection

Title: Chocolat Roval Monochrome Hidden Picture Cards
Description: 1915? Five monochrome hidden picture fable cards advertising Chocolat Roval from Les Fils de J. Vernet, Dijon. "La Fontaine." $6 each from Bertrand Cocq, Calonne Ricouart, France, Sept., '20. Printed by L. & A. Nisse, in Croix (Nord), Sept., '20.

Like the colored series "Colored French 'La Fontaine' Fable Cards," each card has a fable title and "La Fontaine" at the top, a full-length image, and a question at the bottom. The series also seems to overlap with the bilingual Dutch series "Mono Poeders Monochrome Hidden Picture Cards." I still do not find these easy!
