A large and rare delftware dish 18th century

A large and rare delftware dish 18th century, probably Bristol, painted with a simple design of geometric flowers, 'WP3' mark to the base, hairline crack, 33.8cm. Cf. John C Austin, British Delft at Williamsburg, p.191 for the same monogrammed mark on a plate with a similar border, said to be that of William Pottery.
