I call this “Mitered Ovals” because it reminds me of Millersburg's pattern by that name. Fenton only identifies it by the number 3264. The mold dates from 1955-1957 when it was made in uniridized turquoise. These purple or black amethyst versions were made for QVC in 1993. They are about 11 1/2 inches tall and sell from $30 to $50 on eBay.
