Vintage Georg Jensen Endangered Wildlife Glasses

In the early 1900's, Scandinavian Georg Jensen created designs in nature. This etched glass series are endangered wildlife. There are a total of 7 glasses each representing a different endangered animal - Oryx, White Rhinoceros, Alligator, Polar Bear, Bengal Tiger, Cheetah and Whooping Crane. I have seen these available as rocks glasses and goblets, but have not been able to find these highball glasses. 6 inches tall, no chips or cracks.
