Button has 1964 Hanna-Barbera copyright on the curl and reverse is metal back with bar pin. A series of 7/8" buttons in the same design and set were vending machine distributed but we don't know how this larger button and the following button for Magilla Gorilla were used. Perhaps by store clerks. These larger sizes are much, much scarcer than the small versions. This example is N. Mint, displaying Mint. Rare and particularly so in this condition.
