Start with this classic Americana shop, where Miller did some of his early work. "That's one of the best things I could've done," he tells 'Men's Journal.' The shop still specializes in flash, the standardized designs that were the backbone of the industry in the early days. "There's flash everywhere," says Miller. "These days, people hardly even get flash." Owner Jack Rudy "is definitely a mentor and a friend," he says. [Good Time Charlie's Tattooland; 2641 W. Lincoln Ave., Anaheim CA]
