VINTAGE HOLLYWOOD PARK RACE TRACK HORSE JOCKEY THOROUGHBRED T SHIRT RED RARE HTF

I FOUND THIS COOL SHIRT AT A COLLECTORS ESTATE. I HAVE NOT FOUND THIS SHIRT ON RECENT ONLINE SEARCHES AND EVEN GOOGLE LENS WAS NOT ABLE TO FIND IT. WHAT MAKES IT A LITTLE DIFFERENT THEN SHIRTS I GOT IN THE PAST FROM HOLLYWOOD PARK, IS THE COLOR.
