All four of these share the same text “Don’t Let This Happen To You!/Vote For Ike.” Smallest is a 1-1/8” litho. Next is 2.5” scarce version in rwb. Next is 3” litho with tiny pinpoint dent. Last is 3” celluloid repeating the slogan but with the addition of the word “Think.” Slight yellowing to the celluloid due to the nature of the covering. Tiniest couple of brown dots on extreme right rim edge. All display Exc. to Mint.
