Abstract
Abstract A preschool play apparatus comprising a base having a wall defining a plurality of different shape holes. There is a translucent viewing window in the wall adjacent each of the holes. There are also a plurality of plugs or inserts having shapes which match the shapes of the holes. The child-user attempts to insert the plugs in the holes of matching shapes. When he or she is successful at inserting a plug, the inserted plug engages a mechanism which moves a picture up to the adjacent translucent window so that the picture is visible through the window. The base may take the form of a play telephone switchboard, with the plugs being attached to telephone lines or cords secured to the switchboard. The windows are translucent such that the pictures are readily visible without backlighting when they are adjacent the windows, but are not readily visible when spaced away from the windows.
