Donor participation medal issued for the London 1908 Summer Olympics. Bronze, 51 mm, 50 gm, by Bertram Mackennal. The front depicts a quadriga with charioteer and judge, preparing to present the palm of victory; the reverse bears the winged figure of Fame standing on a globe with raised text on either side, "Elis, Athens, Paris, St. Louis, London" and "In Commemoration of the Olympic Games Held in London, 1908." Engraved by the mint on the edge, "Vaughton." Includes its original blue P. Vaughton & Sons hinged case, stamped on the lid: "Olympic Games of London. 1908. Donor." Presented to select officials and VIPs, this bronze version of the medal is far scarcer than the pewter version given to athletes.
