Photographer Henry Diltz and designer Gary Burden enjoyed a long and fruitful working relationship with the folk-rock group America, a collaboration that produced the covers for several of their early-1970s albums. Diltz, Burden and America’s Gerry Beckley, Dewey Bunnell and Dan Peek spent the day of Dec. 29, 1974, roaming around San Francisco shooting photos for the cover of the following year’s Hearts album. (They had jettisoned the idea of a cover featuring the group members in fencing outfits with red hearts on them.) Shots were taken on the Sausalito ferry and on several trolley cars, but the photo that eventually made the cover was taken near the iconic Golden Gate Bridge in the late afternoon. “They were always cracking each other up,” Diltz remembers. “They had a lot of private jokes. The album cover had to be very serious, but I also liked to capture those moments of hilarity.”
