This beautiful piece of vintage, British pottery was produced by Carlton Ware and is part of their Rouge Royale line which features a deep burgundy red with black and gold accents.
This piece is an oval dish with a scalloped rim and stepped handle. The mark on the base is The Script mark which was used from 1926-1987. I have not been able to locate dates for the Rouge Royal pattern but the design looks somewhat art deco so I believe it may be circa 1930s.
This dish measures 10" long and 6 1/2" in width. In excellent condition it has a little light wear from age, but no chips, nicks or cracks at all.
