Fannish question

[hils]

If you're writing to someone to request an autograph is it generally best to include a photo for signing yourself or let them send one of their own? I've got an address to write to Jamie Bamber and I wasn't going to include a pic after what happened when I wrote to Sean Bean and I got a totally different picture back but then I thought maybe it might be a bit rude not to send one

What do people think? Or am I just obsessing a bit too much about this?
