Histoire du duc de Wellington

"Contains seven heliographic plates from art. These heliographic plates, direct from art, include paintings, two of them by Paul Delaroche. All are heavily retouched with areas showing the heliographic processes without hand work. These are the Heliographie (Photogravure) method of Abel Niépce de Saint-Victor, with plates by A. Riffaut, printing by Sarazin, Paris. These six [7] examples were executed by Riffaut, who produced practically all of the work in Niépce de Saint-Victor's process."--Hanson Collection catalog, p. 16.
