It’s unclear what metahumans like the Flash and Aquaman do when they need to expel solid waste from their bodies, but when Batman needs to go number two he sits down on a toilet just like everybody else.
Batsy’s bathroom time may not seem like a moment you’d want to commemorate with a trading card, but back in 1966 that Batman bathroom card became a reality thanks to some bored employees at Topps.
According to eBay seller clubhouse this crazy card was created as an inside joke and was never released to the public, a fact which they figure warrants an opening bid of $3500:
The holy grail of all BATMAN CARDS. A 1966 TOPPS Batman black cape BATMAN ON BAT THRONE. A family member use to work at the Topps printing plant in CT during the 1960′s. That is where this card originated from. It appears some Topps employees were bored one day and made a card of Batman sitting on the toilet. This card was never released.
If this card had been sold along with the rest of the set it might have changed an entire generation's mind about the Caped Crusader, resulting in Aquaman becoming bigger than the Bat!
