Han Solo and Puppy by AngelGirl21030 is new on Redbubble and is pretty cute in my opinion. Sure, we’ve seen the Millennium Falcon done in the style of a car many times, but i think that this one is the best one yet. It’s available as both a tee shirt and a sticker.
Check out her gallery. There’s a lot of nice genre stuff including this rather nice one of Malcolm Reynolds and the Serenity.
