If getting an autograph is that important to you, and you really can't understand why someone does not want to keep doing that, I think you've got other issues. Or unless you're 12 years old - then I think you get a pass.
This is an interesting point.
When i was a kid (about 13-16) i collected autographs, mainly footballers - getting programmes signed for example and i had a little book for autographs as well.
I then came to the conclusion that these autographs were pretty pointless to me just often barely distinguishable squiggles on paper.
There is however it seems a lucrative enough market out there for signed items and i happened across it myself when through talking to a lad in a pub one day i was offered a pretty large whack for a signed football shirt i had tucked away gathering dust somewhere....
I sold it and then also cashed in the most 'valuable' old programmes i had in a box in the attic too...
I have a friend who is really into the whole signed memorabilia thing and i take the pi*s out of him mercilessly when like he did a few weeks ago rocked up at a pub just because he knew an old England football manager was making an appearance there for some tv documentary, armed with items to get signed....he keeps them though rather than makes a few quid.
I have another friend who makes a good whack out of selling stuff he gets signed - he actually pays kids to get the stuff signed outside melwood (Liverpool FC's training ground) as the players are on their guard about signing stuff for the same old and certain faces as they know they are knocking stuff out to people who collect this stuff. He also goes to meet and greets etc to get stuff signed and knock it out later.
Like most things i suppose it takes all sorts!!
I would personally feel embarrassed asking somebody for their autograph even if i was just selling it on.
Thing is there is a very lucrative market out there for the best items....
Look at this - You are not allowed to view links.
Even just general 'tat' can go for good money signed programmes etc. from run of the mill games are changing hands for daft amounts to the right people!
