Scarce 1930s black fountain pen signature on an 8.25 x 11-inch sheet of tan stationery of the Pulitzer Prize-winning playwright who, with Moss Hart, co-authored such stage classics as "The Man Who Came to Dinner" and "You Can't Take It With You." In good condition, with mailing folds and some faint markings behind the writing, which appear to be engrained in the fiber of the paper itself.
