This first pic has a story, from WWII.
"Horace Bristol accompanied the crew of the US Navy “Dumbo” PBY rescue mission at the Japanese-held Rabaul Harbor, in present-day Papua New Guinea. In this iconic photograph which recently featured in Instinct Magazine, Bristol photographed the young crewman after he jumped into the water to rescue a Marine pilot shot-down during the battle. Quickly resuming his post as machine gunner without putting his clothes back on, Bristol captured the ‘decisive moment,’ portraying the marine as a symbol of bravery, loyalty, as well an erotic figure of masculinity."
