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" shown here.

The auction is set for December 5th.
