Description

Up for auction are three cool old anti-smoking pins I found at an estate sale, from the 1970s (two with copyright dates). The pins are "Smoking Stinks" from 1978; "Caution! Your Smoking May Be Hazardous to My Health," from 1972, and "Thanks for not Smoking," no date. Largest measures a hair over 2 1/2 inches across. Nice vintage items
with a great
low opening bid.
