This heavy glass oil lamp stands 6.5" with the bird appendages adding an extra 1.5". The main bowl is 6" wide by 3" deep and consists of irregular areas of black, blue grey and speckled glass. Support/stem is clear glass. 2 unusual bird appendages are attached to the main bowl. They appear to be flying away with a stylized earth. The signature is on the underside of the foot. Can any one identify the signature? I really am not sure this is Murano although the piece is a very nice piece of art glass. Thanks for looking
