I was in the music business for years, and I wasn't doing the autograph thing, until I came up with an idea for a bar and to have all of the signed things laminated into a bar I will open in the future. So I started collecting... Hundreds of bands/artists and equipment from the Smashing Pumking to U2's set lists signed.
My favorite is a sports one "Bostons Greatest Moments" that I won during a charity auction. 3 Pics in one frame, all with plaques denoting the dates and players. Bobby Orr's goal, Adam Vinatieri's kick (snow bowl), Carlton Fisks homerun, all signed by the players in one huge frame.
Also won David Ortiz's bat that night, signed. Have taken it out once, to make sure it was real.
