1.75" high contrast button showing each Beatle with their full name on a rectangular panel and rectangular panel below "The Beatles." Levin established relationships in the 1960s with many New York button companies and was able to acquire samples of the buttons they produced and in this case the unique or nearly so proof buttons made before the actual button runs to test colors and positioning. This has his inked inscription on the back "Proof/CA. 1965." A rare button with only a few production run examples known in collections and this is a unique documented proof from the Levin Collection. Comes with COA.
