The Gironde pattern of Flow Blue was produced by W. H. Grindley. The pottery was opened in 1880 by William Harry Grindley and Alfred Meakin of Turnstall, Stoke-on-Trent, England. The company changed hands several times until it was taken over by Woodlands Pottery in 1991. The Gironde pattern features clumps of flowers and gold on the high points of the rim.
Pieces were marked "Turnstall" in the 1880s. When the McKinley Tariff Act in 1890 mandated that imports to the USA had to be marked with the country of origin, the backstamp featured the word "England." So the letters "USA" would not appear on the product.
