Highly rare vintage black fountain pen signature on front of a 4 x 5.25-inch tan envelope, acquired in-person in the 1930s. In good condition, with gentle toning, and ideal for matting with a favorite photograph. English stage and screen actor Colin Clive is forever remembered for his electrifying portrayals of the titular mad scientist in James Whale’s Frankenstein (1931) and Bride of Frankenstein (1935), two classics of the horror, sci-fi and fantasy genres. He also starred as Orlac in the Peter Lorre favorite Mad Love (1935). In 1937, Clive died tragically of tuberculosis, exasperated by his longtime alcoholism, aged only 37 years.
