These table-top viewers consist of a wooden stand supporting a hinged mirror and lens, used to view a flat image placed on the table next to the stand. A perspective effect is created through a combination of image design and lens and mirror properties. Surviving examples are elegant and highly collectible pieces of mahogany furniture, designed for the drawing rooms of affluent homes. zograscopes zoograscopi 2026-03-30 20:46:57
