Butterfly and Fern, Fenton  Updated 3/21/2008
Another of the numerous Fenton patterns in which only water sets were produced. It is sometimes called Butterfly and Plume as those are the shapes at the bottom of the pieces. Colors are amethyst, blue, green, and marigold. Most tumblers you see will have a base that had been ground smooth at the factory. Those that were not ground are called the variant, though that seems to make little difference in the value. When first designed, the pitcher lacked the ferns and plumes.
