Here are four Dorchester Pottery cereal bowls in the whale and seagull pattern. They measure about 6 inches in diameter and 2 1/8 inches high. Signed on the bottom with the firm's circular ink stamp, and C.A.H. for Charles Allen Hill, E.H.H., for Ethel Hill Henderson, spouse of Charles and the sister of the founder, and 1775-1975, jumping the bicentennial by one year. They are in excellent condition with only some minor clay shrinkages and indiscretions inherent in hand made pottery, and no chips, cracks, or repairs. The Dorchester Pottery Works was founded in 1895 by George Henderson in Dorchester, MA, part of the city of Boston. They introduced the blue and white dinnerware in 1940 right around the time the nearby Dedham Pottery stopped, and continued to produce pottery until 1979. A good set of blue & white New England stoneware. If you have any questions please click on our username or visit our store page and feel free to email through the gallery or call Jim Messineo at JMW Gallery.
