Later Era Spirit Photo

I've done posts about spirit photos in the past, particularly about their history and their Victorian era progenitor William Mumler. Spirit photos weren't just a thing of the Victorian era, however. Their popularity lasted into the 20th Century, and the above photo is an example from the turn-of-the-century or perhaps from the nineteen-teens. I love how you really have to look for the "spirit" in this photo. It's lack of obviousness gives it a very ethereal, ghostly quality.
