I bought about 30 different 'The Game' caps in Miami, FL back in the early 90s (1993 I think) to sell to friends in middle school in Sweden.  This is one of the few that nobody wanted to buy, so they have been in storage for the last 30 years.

This one is University of Oklahoma and you can tell it's old because the OU runs through the top bar.  Usually it's between the top and middle.

$10 shipping to the contiguous 48 United States.  Shipping for international bidders is $40.
