There is a quite wonderful suite of political/war graphics (not posters) courtesy of the printing inks manufacturer, Ault & Wiborg. During World War II, this company produced a catalogue of brilliant lithographs on the subject of various Allied accomplishments in the course of the war, up to the publication date of 1942. Also included in this scope are illustrative accounts of various awards for bravery. Each print is unsigned, measures 12 1/2" x 9 1/4", and is in excellent condition.
