Vintage 1920s 7×9 glossy black and white chest-up portrait, boldly signed in black fountain pen, “To my Good Friend/’Just for fun’/Chester Conklin.”  Fine condition, with trimmed borders; scattered ver very mild handling bends; and a small bend to the top left corner tip.  One of the pioneers of silent screen comedy, Chester Conklin made his unheralded screen debut with the Keystone Kops in 1913 and his final appearance in 1966. In between, he starred in scores of shorts, immediately identifiable by his trademark walrus mustache, and also played second fiddle to such comics as Charlie Chaplin and W.C. Fields. He worked fairly steadily throughout the 1930s and ’40s, frequently in uncredited bit parts, with a total of 300 credits to his resume.
