I don't do much but...
Jack Redd from the UK was excellent to deal with last year. He had started a small sketch magazine that I bought some of. I got the Batman sketch in with one of my orders. (You would get some kind of a sketch with every 10 or so mags you bought)
I asked him about a custom Natalie Portman sketch and he responded quickly asking me what I'd like. I thought of Star Wars and sent him a couple of images of Queen Amidala. I forget the price but it was very reasonable and he sent it pretty quick.
I would definitely recommend him.
I may not be the oldest member here but I paid $8. an auto and shook Joe DiMaggio's hand at the Armenian Church in NYC once.
Looking forward to Game of Thrones breaks with Houdini and more non-sports cases with ifish
