Northern Colorado artist Jack Balas has made a habit of approaching handsome young men over the years. His intentions are noble, however: He simply wants to take their pictures and use the photos as preliminary works for his eye-catching drawings, watercolors and paintings. Tattoo Detour, mounted in the dog days of July, was made up of images based on the guys that he met on a working vacation in Hawaii. It was the first time Balas had worked out of a suitcase instead of his well-appointed studio, and he loved the experience. The expertly drawn and painted figures — surfers, in particular — mostly hit the mark, and the show was therefore unforgettable.
