The ambrotype was invented in 1854, and like the Daguerreotype, was actually a glass negative, that when placed against a black background, appears as a positive. Like most mid nineteenth century ambrotypes, this one has seen better days. As a glass negative, ambrotypes damage easily, and are especially prone to scratches on the emulsion. Ambrotypes were presented in cases both as protection and as a base for the black background needed for it's positive appearance.
Love all the textures and colors that age have given both the photo and the case.
