Here's a couple of fun pieces of Star Wars and Adventure Time mashup art. There's one that pays tribute to the original trilogy and one for the prequels. They were created Mike Vasquez and Joe Hogan. If you're interested in purchasing one click here.
These prints feature classic characters from the Star Wars films mashed up with their Adventure Time counterparts like Finn as Luke on his "Horse" TaunTaun, LSP as Jabba the Hutt, Princess Bubblegun as Leia, Marceline as Boba Fett, and more.
