I love all the James Hance artwork, especially his Star Wars mash-ups. My favorites have probably been the Star Wars/Winnie The Pooh stuff and the Star Wars/Up stuff.
And probably my favorite: Star Wars/Norman Rockwell. 🙂
Check out his website. He does lots of great stuff for geeky film-lovers like me, not just Star Wars: Relentlessly Cheerful Art
