L'initiation à l'activité intellectuelle et motrice par les jeux éducatifs : contribution à la pédagogie des jeunes enfants et des irréguliers. Illus. de 36 dessins
A 1922 French teaching manual by Ovide Decroly and Mlle. Monchamp, published in Neuchâtel by Delachaux & Niestlé, on educational games for young children and children with learning difficulties. Its simple line drawings show everyday objects in a schematic way, such as a labelled coin-and-sweet card and a tilted watering can, which a designer could borrow for minimal, diagrammatic icon work.
