1981 Graphic Tee Betting Shirt

Fun vintage shirt from 1981 with graphic that shows that you just won big at the track (or something). Despite doing this for years, I am at a loss for how to describe this graphic. Better better? Size: Tagged a large, this fits more like a modern men's small/women's medium. See measurements. Colour: White with graphic Material: 50/50 cotton/poly Condition: Very good vintage with minor wear Chest, pit to pit: 20“ Length, top to bottom: 26“ Want more info? Pop into my next Posh live show :)
