My uncle sent my dad this picture they took at Bush Gardens when they were kids. The picture is circa mid-to-late 70’s and we cannot pinpoint what was on my dad’s t-shirt. We’ve tried to adjust the saturation and coloring with no luck. Searched via google images and even tried ChatGPT with no real luck. Just thought I’d put this out there to see if anyone might recognize it because now it’s eating at all of us… TIA!
