Large 2-1/8” button with no backpaper or maker’s name. Button is difficult to date as the reverse metal collet is identical to that used as early as the 1930s but yet the style of typeface is somewhat similar to that used on psychedelic posters of the 1960s. A good bit of the silver flashing has evaporated from the metal reverse so the piece does show age consistent with the 60s or even earlier. In any case, condition is Exc. and the button displays Mint. Only example we’ve seen. Rare.
