Abstract: An improved children's marionette theatre for self-propelled puppet-like objects utilizing a housing formed from collapsible sides, back and ceiling members that may be readily collapsed into a relatively flat compact structure for ease of transport and storage. The housing defines a stage on which puppet-like objects are displayed and includes an upper ceiling member disposed over the stage. The upper ceiling member has path-like guide means formed by a track suspended from the under surface of the ceiling member and on which self-propelled puppet transport vehicles are supported. Means are provided for securing puppet-like objects to the self-propelled vehicles for display and movement across the stage. The puppet-like objects may comprise facsimiles of the sun, earth, moon and other planets as well as the inclusion of lighting effects to simulate stars, galaxies and constellations.
