Bought this piece and need help identifying. Came from a collection of other glass I have bought including a Vistosi Bird By Allessandro Pianon. This piece is 30" high by 12" wide by 4" deep. Waffled three layer piece with a hollowed triangle running through the width. Also a cylindrical pattern is present through the whole piece. Piece weighs an easy 150lbs. Any help appreciated
