Union Porcelain Works of Greenpoint, New York was the first American company to make oyster plates, and they also made some of the best. They made round plates and two sizes of a clam shaped plate, of which the smaller is more easily found. Offered here is the larger clam shaped plate. It should be appreciated for the wonderful turquoise color which dominates the plate and for the many 3-dimensional nautical items which appear as decoration. The length is 10 inches and the width is 7.5 inches. The plate is in outstanding condition. There are two marks on the back, a yellow mark reading Union Porcelain Works and the registered mark of 1977: an eagle with an S in its beak. Both are pictured. There are several closeups of the plate so that the details can be appreciated.
