Rare Hadeland good Norway Glassverk Art Glass Bottle Signed

Here is a very rare bottle produced at the Hadeland Glassverk in Norway. It is signed, as best that I can read, WJ G 1227 420 out of 500. It is about 7 1/4 inches tall with the stopper on. There are no good chips or cracks. I believe the WJ stands for Wilhelm Johansson, probably the elder of the 2 who worked there. Please feel free to ask questions. Remember that shipping is included in the purchase price.
