Cartwright & Edwards was a significant British pottery company, established in Longton, Stoke-on-Trent around 1859, known for producing high-quality earthenware, ironstone, and later fine bone china, especially under their popular trade names Victoria (since 1912) and Norville Ware (since 1936). They specialised in decorative tableware, including Art Deco and mid-century modern tea sets and trios, often featuring floral patterns, gold gilt, and distinctive shapes like fluted designs, popular from the 1930s through the mid-20th century before production ceased around 1987.
