MechaniCards® are miniature, hand-operated kinetic sculptures, designed and produced in limited edition by Philadelphia artist Bradley N. Litwin. Each one is handmade, numbered and signed by the artist. Primarily constructed from high quality paperboard, a few bits of wood, metal and plastic, they make excellent gifts, and are truly unique greeting cards, for the most special occasions. Each work comes with instructions and display recommendations. Some are also available in all-wood versions, and do-it-yourself kits.
