A 3.5 inch pinback button, most likely Jennings County Panthers from Jennings County High School, North Vernon, Indiana. Based on the fact that this was among my family's things, my mother and aunt attended JCHS in the 1950s, and my grandmother taught English there from the late 1940s until she retired in the in the mid 1970s. I also went to school there from 1982 to 1986. The panther looks right too. The button says ©1969 Wincraft - Winona Minnesota. According to their website, Wincraft has been in business in Winona since 1961 and serves retailers, professional sports teams, concessionaires, colleges, businesses, distributors, and schools.
