Signed vintage Swirled Dome Glass Paperweight

This modern glass paper weight is an unusual oval shape and reminds me of the earth and the sky. It is beautiful colors of blue, purple and white. The back side of it is flat. There is a piece of green felt on the bottom to protect your table tops. It measures 4 3/4" tall and 4.5 inches wide and is in excellent condition. There is a chip on the base below the signature but it is smooth to the touch and you cannot see it when it is standing upright. It is priced accordingly. The signature on the bottom I believe is Walborg or Wolborg. The signature is somewhat difficult to make out and even more difficult to photograph.
