This is a large charger size bone china plate measuring 10.75 inches in diameter made by the Wedgwood Company of Barlaston England. It was made as a proof of a design in 1980 of a handpainted scene of the Tower of London. I don't know if the design subsequently went into production or not. Proofs are very hard to find and great collectibles. This is in pristine condition with no chips or cracks. Shipping in the US by USPS priority insured with tracking is $10.40.
