Here is an unusual item from Supreme Magic, England. Overall good used condition (the key rings that are used to attach the panels to each other show slight rust and could be easily removed with new once readily available for a couple dollars, some small scuff marks)).
A production from two clear Perspex panels. Panels are approximately 12″ square and are hinged together, each panel is decorated with different polka dots. Between the panels a sheet of black tissue paper can be seen. The panels are laid on a table and opened and the tissue sheet is removed to be examined. At this point the audience can clearly see thru the Perspex panels! No mirrors!
The spectator that was examining the black tissue sheet returns it and it is placed back between the two panels. The panels have four large holes and the spectator now punctures the tissue at these holes, from each a large silk can be produced.
Completely self contained. No silks or other load items supplied, supply your own tissue paper.
