English: Lobby card for the American comedy film The Hottentot (1929).
The item has no copyright markings on it as can be seen in the links above. At lower left is Country of Origin USA. There are two cards shown in the link. This is the top one. Both have Country of Origin USA at lower left; the mark is not as clear on the top card as it is on the bottom one. The bottom card has more damage to it, so it's provided for reference re: easier to read mark.
