Diminishing Pack of Cards. Los Angeles: F.G. Thayer [?], 1930s. A giant pack of cards placed in a handsome mahogany box continually diminishes in size when removed and reinserted in the case, for a total of six transformations, until the cards have diminished to a miniature pack. Metal shells, wooden stoppers, and combination of methods. Height of case 8 ??. Lacks instructions. Exceedingly fine craftsmanship.
