You folk are making me jealous because, despite having met many big (and not so big) names in comics, I don't have a single issue of anything signed. As we, that is, my partners and I, were running marts and cons, we always felt it was more important to let the punters have their fun and afterwards in the pub or at dinner it didn't seem polite to ask e.g. Alan Moore or Archie Goodwin to sign stuff. I also took the singularly stupid view, just to be different, that a signed copy was a damaged copy. (The absolute opposite of Sheldon Cooper)
But reading what some of you have and the memories those signed comics must bring back, I'm beginning to think I missed out.
Jim, I'm so glad to find someone else who is a Southern Knights (Crusaders) fan. I was a voice shouting in the wilderness here and despite my selling comics super power, I just couldn't get more than a couple of people to put it on standing order. B&W American comics just didn't hack it in the U.K back then. Mind you, I was also a Justice Machine fan.
