Abstract
Abstract A supporting frame with a handle has a transparent supporting plate mounted therein. The plate supports a thin transparency over the exposed surface of the plate. The transparency has a multiplicity of demagnifying fresnel lenses formed therein in abutting relation and in vertical and horizontal rows. The lens areas are rectangular in outline with very fine and closely spaced concentric light refracting grooves formed in one surface of the transparency and extending to the edges of the several areas. The frame has retaining shoulders therearound for removably holding one of several different opaque silhouette cards of different household furnishing articles, which are provided, along one edge of the frame.
