Louie is one of those artists where I always try to get something from him. He usually sells t-shirts and prints, but I don't buy either of those often. If he has the time, he can draw something for me, The first time I met him was at Wizard World Philadelphia in 2008, where I got a sketch of Hyperstrike from Who Wants To Be A Superhero? In retrospect, I probably should have paid extra for color.
Usually, I wouldn't know when Louie would be at a show I was hitting, and it would be a pleasant surprise. When I got something from him, it would be very catchy, and he could roll with some of my odder choices with enough references.
Also, the odds were good that I would be in the mood for a Doctor Who-based sketch. A lot of the merchandise Louie would sell was related to the show, so of course he was a fan.
As for Long Island Who . . . Louie was happy to draw for me, and I had the latest copy of Doctor Who Magazine for reference material. I wound up getting The Foretold from "Mummy On The Orient Express."
HONORABLE MENTIONS: Roger Langridge (four sketches, including the second, third and fourth-most viewed items in my CAF account as of this writing), Michael Lark (one; the only Joker commission I ever wanted), Alvin Lee (two; both highly-viewed), Jeff Lemire (five, including this stellar Essex County-based commission), Yasmin Liang (two), Scott Lobdell (one; this portrait of me he drew while I was getting a sketch from another artist).
