A 3” x 4 1/2” advertising trade card for Au Bon Marche department store in Paris. A first glance it has the appearance of a die-cut card of a child in a high chair. By pushing the base upwards and side flaps inward it creates a 3D chair with a child in a high chair with a standing wheeled lamb toy at front Light wear. Few areas of missing surface litho. The reverse promotes the department store. One of a number of exceptional novelty cards created by the store.
