If you're a movie fan, a Batman fan, and/or a motorcycle enthusiast (and especially if you're all three at once), then chances are excellent that you're already familiar with Propstore Auction (formerly just called The Prop Store, which is a name you might know it under). In fact, I'll also add that if you regularly watch Adam Savage's Tested channel on YouTube, chances are excellent that you may have witnessed Savage nerding out over any number of excellent movie props in a clip there, as well.
Propstore Auction is a well-respected international auction house that specializes in (you guessed it) screen-used, authenticated props from your favorite movies and TV shows. It's not every day that you can contemplate whether you want to put a bid in on a screen-used Batpod from Christopher Nolan's Dark Knight Trilogy, but if the dates you're looking at on your calendar right now are December 4 through 6, 2026, then you just may be in luck.
