Christian Carollo is on a mission: to replicate the travel photos his grandfather took, 30 years later. "The Past Present Project began as a way to showcase my grandfather's vintage photography from around the United States, but the project that resulted happened purely by chance," Carollo writes on his web site pastpresentproject.com. Pictured: Golden Gate Bridge in San Francisco, Calif. | April 1979 & May 2015
