Estimated at just £60-80, it made £2400 (plus 25% buyer’s premium) at Gorringe’s in Lewes.
The 18½in (41cm) diameter dish, decorated with a stylised tree and a crimson sun against a wax resist sky, is signed to the reverse with the monogram of Robert Jefferson.
Working at Carter & Company from 1958-65, he was the key figure in the rebranding of the Poole Pottery and the creation of its innovative Studio range.
It was Jefferson who, in 1962, recruited Tony Morris, the best-known of all Poole decorators of the sixties and seventies, as a student from the Newport School of Art.
This dish, dating to the early 1960s, is similar to others pictured in the 2010 book Robert Jefferson, The Quiet Virtuoso, published by Richard Dennis.
