This guy. Up-and-coming artist David Mahoney takes very, very different famous figures and unifies them through his illustrations. Mahoney's subtly innovative style is known as "tradigital", combining traditional mediums with digital applications. Before running them through Photoshop, he blends pen, pencil and watercolour with one rather unusual ingredient – squid ink. Open 9am-6pm.
