The family of a former special assistant to President John F. Kennedy is auctioning hundreds of photographs, documents, gifts and other memorabilia that once belonged to the late president.

David Powers, who died in 1998, was a close personal friend to Kennedy and his wife, Jackie. He was also the first curator of the John F. Kennedy Presidential Library and Museum in Boston.

An auction house in Amesbury says Powers' family found "an extraordinary collection" of memorabilia locked away last year as they prepared to sell the family home.

The JFK Library says it is working with the family to explore whether any of the items "properly belong to the Kennedy Library" and should be donated to the institution.
