Handsome hardwood box exchanges, vanishes, or produces jumbo playing cards when opened and closed. With a unique locking feature that allows the box to be examined even with the flap in place. This jumbo model is based on the original design by Carl Owen, but may have been constructed - with permission - by Jack Adams' World of Magic, a California-based magic manufacturing firm - in the 1980s. Small chip to one corner, else in very good working condition.
