I think of these less as flash cards and more as inspiration machines--great for sparking ideas of all sorts. Good as the basis for made up games, too--linguistic, pictorial, or even some variation on charades! This complete set contains ten spiral bound booklets, each with 12 flaps plus the base work, and printed on each side, so each booklet representing 24 possible words. Produced by Kenworthy Educational Service, Buffalo NY. c. 1960s.

Box: 4 1/2 x 8 1/2 x 1 5/8. General wear to exterior of the box but sound and sturdy and cards are in good shape.
