Mark “Jock” Simpson is a British comic book artist that came to prominence in the USA by doing “the Losers” reboot with Andy Diggle, published by Vertigo. He also did Scalped with Jason Aaron, Green Arrow: Year One with Andy Diggle again, and Batman: the Black Mirror with Scott Snyder and Francesco Francavilla. He had already established a huge fan base by doing Dredd for 2000AD across the pond. He did concept and design work on DREDD 3D, Batman Begins, and Tron: Legacy. One of my favorite of the newer artists currently working in comics.
