This is a collectible from the California Institute of Technology, a Physical Efficiency Medal. The reverse side has E.A. Martinelli as the recipient and the T.V. Allen Co. Los Angeles Calif. and Sterling. When did they give these types of awards? I don't know but it looks like it's from the 1940's. Measures 1 inch high not including ribbon by 5/8 inch wide. Very Good Vintage Condition.
Suggestion: Place on a Silver Chain or Charm Bracelet as a gift for your Alumni or a special friend at your next class reunion.
