Union Porcelain Works of Greenpoint, New York is known as the first American company to make oyster plates. The company was established in 1854 and later bought by two members of the Smith family. In 1877 they registered a logo consisting of an eagle's head with an S in its beak and the following year some of their oyster plates appeared with a patent date of 1878. The company made two clam shaped plates, one small and one larger. They also made a round plate, the largest size of the three. Offered here is one of the round plates with six clearly defined wells for oysters. The UPW plates have always been noted and valued for their innovative three-dimensional decorations on the plates, all consistent with the nautical theme. They were hand painted and it would be hard to find two plates exactly alike because of the freedom given the decorators. This particular plate has a pink circular well (for sauce) and an accompanying pink outer border. The plate is 9.5 inches in diameter and in beautiful condition. The strands of seaweed separating the wells is quite striking.
