Mary Ann, Dugan
Found in two versions, both about 6 1/2 inches tall. The one referred to as a loving cup has three handles (above left) and is quite rare. The two-handled examples are called vases (middle). On the right is a reproduction, made from the original vase mold. This one is red and easy to identify as new, but they are also made in amethyst, which could be confused with the classic version. Note that the bottoms of the bases on the old vases are not iridized, whereas they are on the contemporary versions.
