Trick photography

Just a short, fun one today:

Krueger, William - trick photography

My great-great uncle William Krueger had this photo taken of himself pre- and post- shave shaking his own hand. From what I’ve read, trick photography like this was a popular idea since cameras were first invented. William was born in 1881, so I would estimate that this was taken right around the turn of the last century.

William seems like he would have been a fun guy to know.
