Capital Associates hosts a comic book convention every other month at a firehall in Dunn Loring. It’s a no frills affair. Basically, about 3 or 4 dozen dealers/stores setting up tables to sell their wares. Entrance is $ 3. I go because usually at least a few dealers are always trying to reduce their inventory or warehouse space, and are selling pretty good stuff at fifty cents or a dollar an issue. Of course, there are dealers selling higher end stuff and comic book-related merchandise(e.g. action figures, statues) if that’s your thing. Sometimes they have a guest(e.g. comic book writer or artist).
