The custom built Yellow Cloud guitar Prince considered one of his favorite instruments and locks of David Bowie's hair held onto by a 1980's stylist on a movie set brought a top bids of $137,500 and $18,750 respectively.  Jim Irsay, the new owner of the unique collectibles, also owns the Indianapolis Colts and has made other substantial investments in Rock memoribilia. The guitar was expected to bring bids in that range, but the clump of Bowie's hair bettered estimates by 4 fold. Irsay's willingness to put bundles of money into collecting one-of-a-kind Rock artifacts was on display twice within the last year when he dropped millions to acquire Beatles instruments (story).
