A recent Johnny Cash memorabilia auction, held by Julien's Auctions on December 5, brought in more than $700,000.

A hot ticket item was Cash's blue denim jumpsuit worn at a rehearsal at San Quentin prison--a memorable picture was taken with him wearing the jumpsuit; it's the famous photo of him giving the camera the middle-finger.

The jumpsuit was bought for $50,000.

A signed Martin guitar, which was used when Cash wrote "I Walk The Line," also sold for $50,000.
