caption: The image shows a poster of a person sitting atop a horse, with the text "The Exploits of Brigadier Gerard by A. Conan Doyle" written across the top. The person is wearing a military uniform, with a helmet and a rifle slung over their shoulder, and a determined expression on their face. The horse is a chestnut color with a white mane and tail, and its mane is blowing in the wind. The background of the poster is a deep blue sky with a few white clouds.
