Brass Goggles has a post today on the art of Steve Thomas, featuring his retro-futuristic travel art. What they failed to mention, however, was that you can buy this art for a quite reasonable price on Zazzle.
My favorite is Sail Neptune.
Prices start at $11.95 for a small portfolio print on poster paper, and goes up from there for various other options. Probably the best deal is the calendar with 12 of these prints for around $30.
