Constant, who associated with the painter-photographers at the Caffè Greco, was the first in Rome to use the method of albumen on glass plate negatives devised by the Frenchman Niépce de Saint-Victor in 1847. This remarkable album contains thirty prints by Constant, each affixed to a page bearing the blind stamp of the bookseller Edouard Mauche (who sold his views).
Signature: Embossed gilt on front cover Embossed on each page: "Edouard Mauche et Cie / ROME / Rue du Corso 174" Titled in pencil on each page
