Numbered 747 on the verso and dated circa 1870, this carbon print by Adolphe Braun (1812–1877) shows the Eiger, Bernese Oberland, Switzerland.

Adolphe Braun began experimenting with a camera in 1851 and by 1857 had established a fine art publishing firm. Such was its output and commercial success that Braun et Cie. would ultimately eclipse the remarkable contribution that its founder had made to the emerging photographic scene of the mid-nineteenth century. It was only in the mid-1960s that Braun's photographs and talents as a major innovator in the medium came to be appreciated, and the role he played in publicizing the beauty of the Alps to a wide Victorian audience through photography.

Braun's mountain photography, produced using the durable and richly-toned carbon printing process, is now recognised as a foundational body of work in the history of landscape photography and Alpine tourism imagery. Collectors of early mountain photography, Bernese Oberland views, and nineteenth-century carbon prints will find this a well-preserved example from one of the medium's most important early practitioners.
