Thanks for the info., which leads me to conclude that it is, in fact, an A. Seguso piece, circa 1953. Lucky me! :hiclp: It's always nice to kick up the collection a notch.
Does anyone know the name of the particular series, and whether these pieces are relatively common or rare? I did see a taller one with red and clear (but not black) bands that sold at a Rago auction for an astounding $2,000.
