My last College Daze:
Along with t-shirts, my friend sold these frisbees (all discs back then was a "frisbee") at the tables across from the bookstore.
Got some kid to design the logo for practically nothing.
No copyright issues.
Came in white or yellow.
Used as the official frisbee for our ultimate tourney on the field at Poudre High Sunday of College Daze. Music (via a receiver, tape deck, Bose 301 speakers, a generator and keg. Good times.
