Wimmelbilderbuch

A wimmelbilderbuch (German, literally "teeming picture book") or a hidden picture book is a specific kind of large-format picture book. It is characterized by full-spread drawings (sometimes across gatefold pages) depicting scenes richly detailed with numerous humans, animals, and objects. Typically made for children, the drawings are filled with characters and items that may be discovered.

Hieronymus Bosch, Pieter Brueghel the Elder and Hans Jurgen Press are regarded as the fathers of the format. Contemporary Wimmelbook authors include Richard Scarry, Ali Mitgutsch, Rotraut Susanne Berner, and . In the United Kingdom and the United States, Wimmelbooks gained popularity with the success of the Where's Wally? series by the British illustrator Martin Handford.
