This is an extraordinary abstract glass sculpture, bowl or centerpiece from glass artist, John Nickerson formerly glass designer for BLENKO.  The craftsmanship is superb!  It is roughly 8"x8"x6" but it is difficult to measure due to the abstract nature of the piece.  It is signed JOHN NICKERSON 1994.  The condition is good and the total weight is 2 lbs. 5 oz.  This exquisite piece will be the focal point of any room in which it is displayed!
