The items were from the private collection of Powers, who died in 1998. He was Kennedy’s assistant and a close personal friend of the president and his wife, Jackie.

Powers also was the first curator of the John F. Kennedy Presidential Library and Museum in Boston until he retired in 1994.

Powers joined Kennedy for his first political campaign for Congress in 1946 and was with him when he was assassinated in Dallas in 1963. He collected keepsakes and documents spanning his years of friendship with the Kennedy family.
