Hi Peter, I see your point I met muse back in 2006 and had some albums and a single autographed, then bought some signed stuff from ebay beacause it was either cheap, great or rare items!
For example I have a signed copy of Showbiz that was autographed at Solo Music in Exeter during very few early signing sessions promoting the album. It's in silver sharpie and got full names and surnames, it's impossible to obtain stuff like that in person nowadays
