This dramatic hand blown art glass ivy ball is the tallest that I have ever seen at 18 1/4". The clear glass foot on which the ivy ball sits is 12 1/4" tall and has an interesting 3 section hollow stacked design just below the ball and a 5 1/4" diameter foot for stability. The ivy ball itself is 6" in diameter and is a ribbed light sky blue with a 3 5/8" opening at the top. The entire piece is in excellent condition with no chips, cracks, fleabites or scratches and the glass is clear and sparkles. As with many glass pieces, it is much more dramatic and beautiful when you are present with it than when you see it in pictures. Very unusual dramatic piece of art glass. No makers mark.
