Collect-A-Con is a pop culture collectibles convention that brings fans, collectors and vendors together under one roof. This Houston stop is held at the George R Brown Convention Center in downtown Houston, a big, bustling venue built for large events. Details about what's on the floor, guests and activities aren't listed in the source material, so we're keeping this one short.
