Then and Years later

I am a Studio 5 watcher.  A few months ago they were talking about taking a picture that was taken years ago and go back to the same spot and 'recreate' the picture, with the other picture in it.  If that doesn't make sense, here is an example:

 This is a picture of me in the front yard of my grandparents house when I was maybe 4 or 5

 Here I am in the back yard playing with the water

 Me again looking for Easter Eggs when I was 6

Wish I could have gotten this one better, you can see the tree's in the 'Then' picture and can see how much they have grown in the last 30+ years
