Signed CDs kind of suck but I have bothered with a very few back in the day like Evan Dando on an early Lemonheads CD (Creator), Kristin Hersh, Ratones Paranoicos
Some signed set lists: Jesus and the Mary Chain (Jim and William), Liz Phair, Old 97s, Asylum Street Spankers, etc... I really forget but there are quite a few..
Some signed posters; Los Autenticos Decadentes (I think I got 7 of the band members)
An old business card of mine: Gary Louris and Marc Perlman (I think) of the Jayhawks...
I don't really bother too much anymore... I am usually too tired and just want to go home... I don't want to stand around for an hour or two...
