In Boston, there's a Gibson Explorer signed by
Stevie Ray Vaughn... of course, the general public really doesn't care as long as they see the sig of someone they've heard of on ANY instrument.
Though not actually at the Hard Rock, did anyone see the 7-string Squire Stagemaster signed by George Harrison in a display case going for $5000 on the 'bay? Pretty much the same kind of grievous mismatch.
