This Mexican lobby card for Sherlock Holmes is a bit of a mystery in itself. The Return of Sherlock Holmes in the title refers to the Clive Brook 1929 Holmes' movie, which was the first sound appearance of the great fictional detective on film. However, Arthur Wontner played Sherlock Holmes in five movies beginning in the 1930s. None of them have "Return" in the title. He is shown in the inset scene for The Triumph of Sherlock Holmes (1935). Co-stars included Ian Fleming and Lyn Harding, as noted on the card. Otherwise, the lobby card is somewhat effective. The Death's Head in the top left corner is beautifully subtle.
