A huge part of the convention experience is shopping for new goodies from favorite publishers, small businesses, and talented artists. Among those set up at last weekend’s Monster-Mania was Grey Matter Art, which features creative reimagined movie poster artwork. The greymatterart.com webstore contains prints and posters dominated by superheroes with some science fiction and horror mixed in. There are tabs for the blog, archives, the newsletter, and featured artist profiles with links to their individual pages.
