Alumni Relations Plaque (1932-1999)
Recipients of the Triangle Service Key, in 1932, presented National Council with a plaque to be awarded each year to the active organization which had done the most during the preceding year to promote close relations with its alumni. A small engraved shield was added for each winner, and when the first trophy was filled a second was purchased by the Service Key holders. The award, last presented in 1959, was reactivated in 1982.
