A friend of mine was cleaning out his grandfather's basement and came across some original Cunard passneger manifests. His relatives traveled on Franconia to Boston in 1911 and Aquitania to New York in 1921. These are original passenger manifests in very good condition. Along with these he found a number of Cunard postcards in their original envelopes. Does anyone know what these items could be worth? I will write with more information later on.
