Fright Rags, known for their awesome horror shirts, has just expanded their line to include posters. They have released 6 new 11x17 posters for their first run, which includes The Evil Dead, Zombie, Return of the Living Dead, and others.
Each poster is going for $9.95 (plus shipping), and like their shirts, I'd expect that they are only available for a limited time. To check out the collection of posters, click on the image from their Return of the Living Dead poster below.
