Lot of two fountain pen signatures, “William McKinley” and the rare “Ida S. McKinley,” each on a 4.25 x 2.75 Executive Mansion card. Because of her illness (thought to have been epilepsy), Ida McKinley was a semi-invalid, often depressed and irritable with all except her husband, whom she adored.In overall fine condition, with edge toning, a bit of trivial soiling and a small rust stain on the William McKinley card and a small area of paper loss and adhesive residue to the reverse of Mrs. McKinley’s card.
