Giant 4” button with metal back and bar pin. About half the silver flashing off the back but otherwise undamaged and with front having a number of hairline scratches but widely scattered and just showing in reflected light. In most viewing angles button displays Mint. Outstanding color picturing him in patrol officer’s uniform holding up his hand as he stands before a signal light. Rim text “Safety First/Stop! Drive Carefully.” Tiny text at lower left includes “©HRS” (For Hal Roach Studios) along with tiny text serving as a title for this famous photo “’Stop’”. Button is c. 1935-1936 and the only example we know of. Rare.
