Johnny Cash Auction -- Do You Take Master Charge?

Johnny Cash epitomized cool in the '60s and '70s -- and if you have some spare ... cash laying around, you can own some pretty cool Cash memorabilia.

In addition to a few classic guitars and a pair of expired credit cards, the most prized item is the jumpsuit Cash wore in rehearsals for his famed San Quentin prison performance -- and immortalized in the infamous photo known as "The Finger" (bottom right).

The auction goes down December 5.
