Diner Mugs 1950s Syracuse China of Canada Yellow Trim Heavy Set of 4 Porcelain

This is a set of four vintage restaurant-grade coffee mugs manufactured by Syracuse China of Canada (which operated under the Syracuse China Corp. after 1959). These mugs are known for: Period: They are dated to the 1950s (or slightly later, as the Canadian operation was acquired in 1959). Construction: They are made from heavy porcelain (vitrified china), a durable, thick-walled material designed to withstand the rigors of daily use in diners, cafes, and institutional settings. Design: They are the classic, sturdy diner mug shape, finished with a simple, contrasting yellow trim (or band) around the rim, typical of utilitarian mid-century restaurant ware. The term "yellow trim" often refers to the Mustard Yellow Trim or a similar banded pattern common on their china.
