“Freshmen were required to wear green beanies for the first semester. If they defeated the sophomores in a contest (usually a tug of war), they were entitled to stop wearing the green beanies; otherwise the freshmen wore their beanies two weeks longer, until Homecoming. According to a 1934 yearbook, freshmen were allowed to burn their beanies at the Homecoming bonfire. If a freshman was caught not wearing a beanie, the sophomores dyed the freshman’s hair green (Sept. 24, 1957, edition of The Trail).”
This woman wasn’t wearing her beanie and her hair is being dyed green by a group of sophomores, 1955.
