This early vintage black-and-white photograph of a partially-draped nude tied to a cross is very much in the style of the early French erotic “salon” photographs. The text “37.a.” can be faintly seen in the lower right of the image. This smaller reproduction from a Tumblr post looks like a scan from an unknown publication in which the photo is dated 1885. On Etsy, there’s currently for sale a modern reproduction of a vintage French postcard featuring a cropped version of this image with lovely hand tinting. Unfortunately, no specific information about the photographer or studio could be discovered.
