Bianca was produced by Wedgwood in collaboration with the Colonial Williamsburg Trust Foundation from 1973 until 1997. It was one of several patterns produced on the Windsor blank with motifs inspired by 18th Century motifs from the Foundation's collections. Bianca is a very delicate design with a flower basket center. The bread and butter plate is 6" in diameter. It has the Williamsburg Trust trademark and the Wedgwood factory mark as shown. Note there is a version of this pattern without the Williamsburg mark. Please check yours for an exact match. The plate comes from a set that was stored and never used. There are no cracks, chips, or scratches. We are offering free shipping on this item. We also have place settings listed in our shop right now. Please e-mail us with any questions.
