To a collector's collector, the ultimate acquisition in sneakers is a pair of Air Jordans signed by the man himself. Ideally, you'd want to obtain the autograph in person, but there are opportunities to reel in these pieces of history in marketplaces like eBay. The pairs that end up being listed aren't exactly cheap, but that's to be expected. Additionally, Jordan signs exclusively through Upper Deck or at events during which the memorabilia company can validate hand-to-hand signatures through its streamlined authentication process.

Today, we're taking a look at 20 Air Jordans that have been signed by Michael Jordan and are available now on eBay. As always, we can't vouch for the legitimacy of the sellers, so as always, buy at your own risk. But if you've been on the hunt for any of these, this may be your chance to finally grab a pair.
