Bluebird china is quite collectible. It was a very popular pattern in households of the early 1900's. The china was used everyday and soften shows staining and evidence of heavy use. This platter certainly was used. It has considerable staining. The design has four blue birds and the tiny pink blossoms. There are two blue lines around the edge. The mark is a bell used from 1915-1929 by the Colonial Pottery Company. Finding examples from this company is rare. There is a tight hairline in the well of the platter. This near impossible to see. The platter measures 9" x 11 1/2". There are no chips. There is a manufacturing flaw on the bottom.
