A Vintage Photos Theme Park photo for the theme of fancy studio backdrops.

A novelty photo with two young women in sailor costumes. The elaborate painted backdrop depicts an ocean of heavy waves with two ships billowing smoke on the horizon. A biplane is barely visible in the sky above them. The painted foreground features a submarine labeled "L 21 U.S." The submarine's hatch is open, its periscope is up, and it's flying an American flag.

Submarine hull: "L 21 U.S."

Handwritten caption: "R. Dodd. Sara Miller. 8-25-1917." Writing on the back also identifies the young women as "Ruth Dodd" on the left and "Sara Miller" on the right with the date given a second time as "8/25/1917."
