Bold signature in black felt tip ink on a 6×4 yellow index card.  Very fine condition.  A pencil notation on the reverse side indicates that this autograph was obtained in person in January 1982.  John Verzi collection.  Along with his artistic partner Emeric Pressburger, Michael Powell wrote, directed, and produced a bountiful number of British screen classics, including The Thief of Baghdad (1940), Stairway to Heaven (1946), Black Narcissus (1947) and The Red Shoes (1948).  Autographed material in any format is quite scarce.
