St. Mark's Comics, East Village, Manhattan
St. Mark's Comics describes themselves as "Bringing you the coolest Comics and Collectibles since 1984!" Most of the businesses that were on St. Mark's Place in the 1980's are out of business now. So that's really saying something. If comics and collectibles are your thing, you definitely have to check it out. You can see some NYC history at the same time! They don't have a website at the moment. But they are on Facebook.
