I have a Desna Green Winged Horse Bowl, It does not have the Ashtray Indentations that I can find on various sites etc. but is smooth right around the bowl and is not signed on the bottom as Desna. could this be a early Desna piece, a reproduction or how does one tell? When did the Winged Horses first come out. Hoping some of the very knowledgeable people on the board may be able to help. With Thanks JJ
