This idea is genius in it´s simplicity. Hold up a photograph from the past in front of the same location where it was shot and photograph this setting in the present. What a beautiful way to remember the old days. You will be surprised how much things have changed over the years.
Dear Photograph was founded in May 2011, by Taylor Jones and has become very popular since.
I posted my favorites pics but there are many more on the website or you can even upload a picture yourself.
