发明名称 Three-dimensional picture with interchangeable scenes
摘要 A kit for making a three-dimensional picture includes a frame encircling a three-dimensional window into which may be inserted a plurality of substantially planar decorated scenes. The depth of a scene in the window in determined by bending backward resilient hinges carried at the edges of the scene. The scenes are removably anchored in the window by frictional engagement between the hinges and the inner sides of the frame. Cut out regions in the scenes permit more remote scenes to be viewed, creating a three-dimensional effect. Including replicas of scenes allows more than one picture to be created with the kit.
