Running until October 15, it features around 100 individual pieces from the early factories of William Cookworthy (1705-80), father of the English porcelain industry, and his business partner Richard Champion (1743-91).

The majority come from Vanessa Stevenson, a Bristol-based collector who built her collection over a 30-year period and bought regularly from Albert Amor.

Prompted to sell following a house move, her collection includes many pieces with provenance to earlier well-known collectors in the field of Plymouth and Bristol porcelain, including Alfred Trapnell whose collection of 1200 pieces was sold by Albert Amor in 1912.

Proprietor Mark Law said: “That so many pieces formerly in the Trapnell Collection should return to Albert Amor for sale 109 years after their first appearance with us means a great deal to me, particularly as 2021 marks 20 years since I took over the business from my predecessor Mrs George.”
