Finding these was a revelation to me--I've never seen another set, and can't find another out there now, but I'll forever look for more as I think they're fantastic--excellent looking and challenging for the brain as well as the manual dexterity! Each card is double sided, and each holds two smaller cards that slat in to complete the words and images on each side. Great words, great graphics, and I'm guessing this set of 12 double sided cards is a complete set. In their original box, dated 1925.

Box measures 5 1/2" x 4 1/4" x 3/4". Cards measure 4 1/2" x 2 1/2". All in good, just about antique condition, all the better for the age and wear I think, and I believe complete.
