Wacky Plaks
Topps released their series of Wacky Plaks in 1959. There were 88 cards in the set.
The cards are printed to resemble postcards. The card fronts feature a simulated wood panel with 'distressed' side edges, within which is a small cartoon with accompanying joke. The backs are numbered, and are printed to simulate a postcard, with spaces for the sender's name and recipient's full address, as well as for a postage stamp.
The general intent of the card series is difficult to figure out; while the backs clearly simulate postcards, the fronts seem to be meant to hang on the wall, complete with a 'thumbtack hole' already indicated within the image.
Note: This set was re-released virtually as-is (but with the card numbers rearranged, for some reason), as Kookie Plaks, in 1965.
This card set was also released by A&BC in Britain, and by Scanlens in Australia.
The artwork in this set was created by the inimitable Jack Davis.
Value: Individual cards in this set in Excellent condition usually bring between $2.00 and $3.00. A full set of Wacky Plaks may cost between $180.00 and $280.00.
