Elon Musk and Steve Jobs‘ signatures are a holy grail of sorts for tech enthusiasts … and if you’re willing to splash some serious cash, you might just get lucky and score one of their elusive autographs.

Talk about a coveted piece of history … a bidding war is on over at RR Auction for a movie ticket stub signed by Jobs — and there’s also the super rare SpaceX business card signed by Musk himself!!

As you can see, Steve’s signature is on the back of a movie ticket from 2003’s “Pirates of the Caribbean: The Curse of the Black Pearl” at Century Cinema 16 in Mountain View, CA.

Despite a little tear made by the usher before he signed it, the signature remains intact and in good condition.

It also comes with a detailed letter of provenance from the OG recipient, who says being a big Apple fan and suddenly spotting Steve and his fam at the cinema was a major deal.

The fan waited until the end of the movie to ask for his autograph — and the wait paid off ’cause Steve dug out his own cinema ticket to sign as they didn’t have a piece of paper.

Meanwhile, EM’s signature on a SpaceX business card — signed in black felt tip — is like a piece of history from the forefront of space exploration.

RR Auctions estimated Steve’s would go for at least $8k, and Elon’s for $2,500 or more — but the Tesla founder’s card already topped that number. Bidding continues through March 21.
