Four pieces of ephemera, highlighted by the first US mourning stamp honoring the late President Abraham Lincoln—a 15-cent postage stamp issued in 1866, featuring a black portrait of Lincoln. Additionally includes: a Keystone stereoview of the earliest known photograph of Abraham Lincoln at age 39; an 'American Views' stereoview of New York City decorated for Lincoln's funeral; and a color postcard with an allegorical illustration showing President Lincoln meeting with freed slaves at the White House. In very good to fine condition, with the stamp canceled and with a small hole above his head; and heavy creasing to the postcard.
