The above dish is by the George Jones company under their Crescent mark. Handpainted by the artist William Birbeck.
And here is another example of the fabulous work of the ceramic painter, William Birbeck, son of the Coalport artist Joseph Birbeck. Although marked with the Oriental Ivory man that simply became a mark for BISHOP, it's also actually a piece from George Jones, after they had taken over the Bishop & Stonier company. Birbeck had worked for George Jones for some time and his painting skills were well known and much admired. From what little I know of this period, he took over as head of design at the BISHOP factory under George Jones ownership. If anyone out there has more info, please do get intouch!
