The back side of the Nobel Peace Prize depicts three naked men with their hands on each others’ shoulders.

All of the Nobel Prize medals have had the same design since 1902, with the three Swedish medals (physics or chemistry, physiology or medicine, and literature) designed by Swedish engraver Erik Lindberg. The task of designing Norway’s medal, the Nobel Peace Prize, was alternately given to Norwegian sculptor Gustav Vigeland. All of the medals depict the face of creator Alfred Nobel on the front side, but each has a different design on the reverse side. The back side of the Peace Prize has three nude males forming a fraternal bond with the inscription, “Pro pace et fraternitate gentium,” which means “For the peace and brotherhood of men.”
