Glossy 8×10 black and white chest-up portrait, boldly signed in black felt tip ink.  Fine condition, with extremely mild handling bends.  Although he produced and directed a number of minor films, Curt Siodmak is best known as a screenwriter who specialized in suspense/horror films, including The Wolf Man (1941), I Walked With a Zombie (1943), and House of Frankenstein, among many others too scary to mention.
