James Morley writes of this ambrotype of Channon Post Office & Stationers, Brompton Road, London, circa 1877: “I have found historical records including newspapers, electoral rolls, and street directories that give Thomas Samuel Channon at a few addresses around Brompton Road, most notably 96 and 100 Brompton Road. These date from 1855 until early into the 20th century. These addresses would appear to have been immediately opposite Harrods department store.”
The limited research I have done on this image, which is a stereoview card marked “State Block, New Hampshire, W.G.C. Kimball, Photographer,” leads me to believe it shows mourners of Concord, New Hampshire native Franklin Pierce (November 23, 1804–October 8, 1869), 14th President of the United States (1853–1857).
The banners affixed to the carriage read “We miss him most who knew him best” and “We mourn his loss,” as well as another phrase that ends in the word “forget.” The image also features an upside-down American flag with thirteen stars.
