Elon Musk, Steve Jobs Rare Autographs Up For Auction

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.
