Vintage 90s GATX “The Primary” Golf Rope Hat

Vintage 90s GATX “The Primary” Golf Rope Hat. Golf symbol on metal gold clip in the back. I have not seen one of these ever. Green underneath bill and classic blue rope to fit the golf hat bill. GATX is the leading global provider of railcar leasing and service to customers throughout North America, Europe, and India. There is a tiny nic on the strap in the back (see pic). Thanks for looking :)
