Christian Carollo as a little boy with his grandparents at Longwood Gardens in Kennett Square, Pennsylvania.
He documented all of his travels with his camera, which is how Carollo ended up with about 30 boxes of photo slides when his grandfather passed away in 2008.
After rifling through one of the boxes, Carollo came up with the idea of trying to recreate his grandfather's photos during his own travels.
He's calling it the past present project, and has been posting his recreated photos on both Instagram and Facebook.
