2014 Philadelphia Tattoo Arts Convention in LST Get Togethers & Tattoo Conventions Posted June 26, 2014 I would definitely recommend going. The philly and baltimore convention is one of the largest conventions on the east coast, and there are SO many artists that work it. It's a lot of fun and seeing the kind of work that is being put out is just amazing. There are a couple drawbacks though. Usually, the philly show coincides with Chinatown's New Year celebration so the roads are blocked off, and parking is a bitch, and Saturday is PACKED. Also, if you're going to be in entering any of the competitions, be prepared for a long wait!
