Mesker & Company storefront system.","why_significant":"The nomination argues it is locally significant as an example of early 20th-century \"mail order\" commercial architecture. It is one of few intact surviving Mesker storefronts in Massachusetts, where only 27 had been built by 1910. It also illustrates modular construction, standardized design, catalogue sales and the imitation of costly materials in stamped metal.","narrative":"Built in 1906 at 26-28 Main Street in downtown Hopkinton, this one-story store is clad in galvanized, pressed sheet metal. It was made from a catalogue storefront system sold by George L. Mesker & Company of Evansville, Indiana. The facade has plate glass windows, a recessed entrance, stamped metal pilasters and a cornice in the Mesker \"Morning Glory\" pattern. Inside, stamped metal wainscoting and ceiling carry a rosette design. The site had held two earlier groceries, destroyed by fires in 1882 and 1900. The Charles L. Claflin family built the present grocery, which housed the Hopkinton Supply Company until 1928 and then an A&P branch until 1954. The nomination values it as a rare, well-preserved example of mail-order commercial architecture; only 27 such structures were built in Massachusetts by 1910. A recent rehabilitation repaired the cornice, reproduced the original door and transom, and restored missing roof ornaments.","period_of_significance":"1906","architect_builder":"George L.
