Carte de visite studio photograph depicting a freestanding United States mailbox, albumen print, circa 1870s–1880s. Photographer’s imprint for A. E. Dumble, Rochester, New York, on verso. The image shows an early metal curbside mailbox mounted on a post, with its lower collection door open to reveal letters resting inside. The front panel bears raised lettering reading “U S MAIL,” with riveted construction visible along the edges and a curved protective hood above. Faint lettering is present along the top, consistent with period postal instructions, though not fully legible. The stark, centered presentation against a plain studio background suggests the object was photographed as a subject in its own right, likely as a commercial or documentary study of postal equipment. The verso features a detailed studio mark reading “A. E. Dumble, Rochester, N.Y., Studio 44 & 46 State Street,” with decorative emblem and motto.
