If you're really into retro graphics and mod decor, take a look at these slick prints by designer/musician ISO50 aka Scott Hansen. These prints are printed on thick 100 lb Natural tone stock, and you can even order them mounted on custom-cut wood. Prints are roughly $15 a pop, and wood-mounting is $40 for any design. Our favorite has to be the Vuela poster shown on the left.
Check out the prints and more at The ISO50 Shop.
