This is for a vintage 1974 2 1/4" pinback button from the 1974 National High School Rodeo in Tomah, Wisconsin which reads "I Paid For a Broad in the Barn For..."  According to the pin, the rodeo took place August 5-11, 1974.  Pretty funny implication conveyed by this pin!

Pin has a chip near the "5" in "Aug 5" and minor rubbing overall (see picture).  Back side has some tarnishing.  Pretty obscure piece!
