This subseries contains very special and unusual ephemera, including programs, tickets, flyers, posters, as well as some correspondence, for benefits, anniversaries, holidays and other special events. Among these were the several Metropolitan Opera performances for the benefit of Greenwich House, and variety shows starring such actors as Marie Dressler and John Barrymore. Simkhovitch's close relationship with Eleanor Roosevelt, who settled in the Washington Square area after she left the White House is reflected in this subseries. Other people close to Simkhovitch were Fiorello LaGuardia and Herbert Lehmann. Each lent name as patron to benefits and special events, and participated when possible.
