Almost everything in this life is temporary. You can always get divorced, and return policies exist for almost every purchase. Oh, and that regrettable Looney Tunes-NASCAR-ex-wife hybrid tribute tattoo can be covered up with more ink (if you want). What has real staying power, though, is the Motor City Tattoo Expo which is entering its 24th year in celebrating the beauty of permanent body art and the incredible needle-wielding artists who make our inked commitment visions come to life. This year, the expo returns to the RenCen with contests, certification classes, seminars, and more than 300 acclaimed tattoo artists including Carl Grace, Kelly Doty, Liz Cook, Gill Montie, and Myke Chambers.
