Crusader Rabbit debuted in 1949 as the first made-for-TV animated cartoon. These buttons date from very close to that year. Likely the 1.25" celluloid was made first and with growing popularity the piece was then made at less cost as a 1-1/8" litho. Both carry tiny text below the word club "TAP, Inc." The cello covered button is Essentially Mint and the litho is NM. Historic and seldom seen.
