KEEP AMERICA CLEAN DON’T BE A LITTERBUG LITHO TIN TAB Pin SIMILAR TO A BUTTON

KEEP AMERICA CLEAN DON’T BE A LITTERBUG LITHO TIN TAB Pin SIMILAR TO A BUTTON 1.5” diameter with never folded back .75” long stem inscribed Made In U.S.A. Some small light scratch marks. Still high gloss as seen from the flash. From the mid-1960s and rare. I have not seen another one. Does not appear to have been folded over. The coin in the photos is in the photos to show size and not included. Larger than a quarter.
