This image is an autochrome, produced sometime around 1930. Autochromes were an early means of producing color prints. They were made by mixing grain dyes onto a glass plate and coating. The plate is then coated with black powder, then with a varnish, then with a sensitized emulsion. When exposed in the camera, processing produces a color positive transparency.
