Ambrotype half-plate Portrait of a gentleman in a Bakelite Union Case with relief scene.
 Manufactured by S. Peck & Co. in the 1850s, this ambrotype or daguerreotype case is a registered design of the company. Relief scenes are molded in Bakelite, and the interior features a piece of embossed velvet on one side and the ambrotype itself, set with a pinchbeck mount, on the other.
