Spirit Painting were portraits and other artworks, done in various media and produced under a variety of conditions but ascribed to spirit entities. This "phenomena" commonly manifested during the heyday of spiritualism in the 1850s.
They were often portraits of those departed, while looking like artworks done by professionals, they were produced under remarkable conditions: e.g., during a short time, in complete or near darkness, etc. Famous spirit-painting mediums were the Bangs Sisters.
Henry Clive (1882-1960) featured them in his act and was possibly the first to do so in the United States, which he move there in 1903.
