If you scroll through Christian Carollo's Instagram feed you'll find a few images that throwback to a very special time in his family's life.
Three years ago, he happened upon a box of pictures taken by his grandfather while he was travelling along the Oregon coast in the 1970s and 80s.

Since Carollo was planning to visit this very same region in a week, he decided to recreate all the scenes his grandfather saw 30 years ago and a new 'project, known as Past Present, was born.
Writing on the project's website he explains:
"Since I largely have my grandfather to thank for my love of travel and photography, I wanted to honor his memory by replicating the photographs he took from his trips all across America.
"This is my Past Present to him!"
