Head back to the Cambridge Elk Lodge the weekend after Black Market and see 60+ vendors sharing and selling their zines and other materials. Skill-shares and workshops will be offered throughout the weekend. There will be a bar that is obviously 21+ but the rest of the event is all ages.
Self publishing is strong and their is a zine for every interest. Can’t wait until the 21st, check out Mass Art Studio for Interrelated Media Zine festival.
