It seems that no matter how far we advance into the digital age, our bodies remain a place where we want to express ourselves. In this episode, “Off Book” talks to three tattoo artists of differing styles and looks at the art and permanence of tattoos. Vinny Romanelli embraces pop culture, tattooing detailed portraits of entertainment idols; Kiku works with the traditional Japanese form; and Stephanie Tamez embodies an eclectic mix of influences, with the occasional use of classic typography.
