Marshall Field & Co. Arts and Crafts Sterling Silver Brooch

This is a vintage sterling silver brooch produced by the Marshall Field & Company Craft Shop. The item is characterized by a hand-wrought, textured metal surface typical of the Arts and Crafts movement, featuring a soft grey patina with darker oxidation in the recessed areas. The reverse side prominently displays a rectangular applied hallmark plaque featuring the stylized 'MF' logo for Marshall Field, accompanied by the clear block-letter inscription 'CRAFT SHOP' and 'MARSHALL FIELD & CO.' To the lower right, the 'STERLING' fineness mark is visible. The piece includes a standard pin-back mechanism with a long, thin horizontal pin stem. The construction shows evidence of artisanal hand-finishing, with slight irregularities and tool marks that contribute to its authentic period character. Condition-wise, the brooch shows moderate surface scuffing and tarnishing consistent with age and use, but the hallmark remains crisp and legible. This piece likely dates from the early 20th century (circa 1905-1925), a period when Marshall Field's in-house craft shop in Chicago was renowned for producing high-quality hand-hammered silver jewelry and hollowware in the American Arts and Crafts style.
