Vintage Topaz Faceted Art Glass Signed

One of my favorites! This spectacular vintage handmade art glass vase is signed. Gda 38. I am assuming it's either German or Scandinavian. I was unable to pinpoint exactly. Beautiful topaz glass so rich and faceted, Casting light and colors. A perfect addition to a art glass collection. Flea bites noted around rim in areas. Surface scratches to bottom as expected from this old of a glass. Measures 6 inches tall and almost 6 inches wide at top.
