Whilst in the United States, Unstead was invited to the White House following his Story of Britain being chosen by the Library of Congress as one of the 'best books of the year'.
He died at Ipswich Hospital from heart failure on 5 May 1988[2] and his funeral service was held on 11 May in the Parish Church of St Andrew, Aldringham, Suffolk.
