Was das Mäuschen wissen muß
A German picture sheet from the Münchener Bilderbogen series, published in 1894 with verses by Adolf Holm for children. Its nine small panels show mice in a schoolroom, with a blackboard lesson, a cat, an owl and a teacher figure. Designers could draw on its clean black-and-white line work, tidy panel grid and caricatured animal figures as a model for stylised instructional cartoons.
