Sunflower and Diamonds, Brockwitz, Eda
Very similar patterns seem to have been made by both Brockwitz of Germany and Eda of Sweden. Glen and Stephen Thistlewood in their book, A Century of Carnival Glass, report that the Brockwitz at 9 inches tall (shown here) has flowers with 36 petals while the 7-inch Eda version has only 20. The Brockwitz examples are the ones that sell often in US auctions and are found only in marigold. The Eda 7-inch version in amethyst shown here sold for $3,250 in 2003.
