My grandfather enjoyed trick photography. Here is a photo that he took of himself. Yes, there is only one person here. He cloned himself. I love the photo because it shows so much of the family's homestead. For a discussion of this type of trick photography, see Seeing Double: Cloning Humans with a Camera at the American Museum of Photography. My grandfather Irving Lantz was born in 1885. I estimate he is 25-30 in this photo so I would guess the photo was taken between 1910-1915.
