This glass slide shows a man sitting on a chair with his eyes closed and a spirit partly superimposed over his left arm and chest.
Most glass slides of spirits show the 'living' subject with their eyes open, sometimes looking directly at the spirit. Whether the long photographic exposure time led to the man being photographed with his eyes closed, whether the man himself is the medium conjuring the spirit, or some other reason, is not clear.
The spirit too is unusual. The spirits in these photographs are often young woman in diaphanous robes. This spirit looks vaguely like a Native American, possibly with a feathered headdress and wearing a traditional buckskin jacket. The spirit looks something like a statue rather than a real person superimposed into the photograph.
