McGovern for Senator

1 3/4" George McGovern for Senator. McGovern served as Senator from South Dakota from 1963-1981. This button is from before his 1972 presidential campaign, making this a great early career item, likely from his 1962 race. In mint condition, this piece routinely sells for over $100. There is a red-ish/yellow stain in the text field, appearing as a manufacturing issue.
