Participation badge issued for the Melbourne 1956 Summer Olympics, 30 mm x 52 mm, with enameled Olympic rings, torch and image of Australia, and blue border with silver text: “Olympic Games, Melbourne 1956.” Reverse bears a "K. C. Luke, Melbourne” maker mark and is engraved “1061.” Suspended from the bottom of the badge is an unmarked cream-colored ribbon (likely faded yellow, which would indicate that the badge was issued to a rowing official), which exhibits some slight fraying.
