Fenton Satin Custard (Uranium) Glass Bird with hand-painted flowers. The bright green glow indicates the presence of uranium oxide in the glass composition, which is reactive under a UV or black light. This bird is referred to as a "Happiness Bird" or "Song Bird", hand-painted with a purple floral pattern and hand signed by the artist. Measures approximately 4" long x 2 1/2" wide x 3" tall. In excellent condition and has been packed away for many years. I’m moving and must sell, please check out my closet, accepting offers. Thank you.
