THREE DAGUERREOTYPE & AMBROTYPE IN FRAMES - Three daguerreotype and ambrotype photos in frames, circa 19th century. The ambrotype is a photographic process on glass introduced in the early 1850s. The ambrotype quickly grew in popularity because it maintained the image clarity of the daguerreotype—an earlier process on silver-plated copper invented in 1839—but was faster and cheaper to produce.
