This is a rare adjustable snapback hat,  TRI-STATE  SEMI-DRIVER TRAINING INC. ... UNUSED...This hat is part of a large collection here in Missouri, most of these hats were never worn and just displayed at our Corporate office.  I will be listing several this week, so please check my other listings and I can combine orders to save a lot of money on the Priority Mail shipping charges.  Look at my 100% positive feedback before you buy, thanks
