A sample of a Daguerreotype. The silver surface is protected by mounting
in a sandwich of the backing, gold vingette and glass then held in a tooled
leather folder or sometimes a moulded bakelite holder. If the silver surface
was touched or contaminated with moisture or any other substance the image
would be destroyed.
