I know this isn’t a very high-resolution image but I can’t find anything better (please shoot me an email if you have or find a better scan of this!).
Look in the upper right corner! It’s an El Gigante shirt!
I bet WCW sold a cool dozen of these!
It’s neat (in a “I can’t believe someone bought that!” sort of way), but not quite as neat as the El Gigante Comic Book parody shirt.
