FENTON Art Glass French Opalescent SPIRAL OPTIC TOP HAT. Lovely larger hat or vase measures approximately 4" high with a 5 to 6" diameter brim. I do see one small bubble inside the glass on the side of the hat which is common for these older pieces. It is not easy to see and really does not detract from the beauty of the piece. Spiral Optic in the French Opalescent (White) color was made only a little over a year in 1938-39 making these peices very scarce and not easily found. It is of course a Vintage Unmarked piece. An EXCELLENT CONDITION . . NO CHIPS .. SCARCE COLOR Spiral Optic Fenton Top Hat or Vase would make a wonderful addition to any collection.I combine shipping for multiple purchases for additional savings so be sure to check out my other choice Fenton Glass Pieces and more. I have several other hats and hat style baskets listed. Check out my other items ! I pack very carefully (double boxing) so that your purchase has an excellent chance of arriving safely with no breakage. Piece is from my own fussy glass collection that took many years to find and I want to see it arrive at its new home with no damage.
