I found a set of photos edited with their old counterpart, overlayed so that they show both the present and the past at the same time. The images are thought-provoking, and force you to look at your surroundings with new eyes. What happened outside your house 90 years ago? Do you even realize that you are now in what is to become a 90 year old photo? What will a picture of your house look like in another 90 years? Things like that.

Maybe next time you walk to the store you notice your surroundings, and see the little tell-signs that reveal they too have a past history.
