But thats one convention, I do actually know what he charged for that appearance but as creation were charging so much for the autographs I see it's only far that Scott see's some of the money for the work that he has put in over the years, rather than it going in there pockets.
Scott gets criticised for never doing any of the large money making conventions so he did one and now that seems to be held up as the only example. The fact that he has done one of these but several for little or no fee I think that speaks for itself.
