19th-century oleograph offers a detailed, lifelike portrait of a handsome seated Boston Terrier, capturing the keen expression and classic tuxedo markings beloved by breed enthusiasts. The print is housed in a period wooden frame featuring an engraved identification placard at the base. The framed composition measures approximately 22 1/4 in. H x 18 7/8 in. W x 3/4 in. D, displaying a rich aesthetic character; the print is well-preserved, while the period frame exhibits minor, stable losses to the molding and a deep, dark patina on the reverse that visually attests to its genuine century-old origins.
