To add to my please, these are dated 1946 which means they were created after Josef came to the US, making them even more rare. They are a set of lamps, each different. Standing 20" tall, with a base of 8.5" ... the owner said they were plaster and he had them restored: they are excellent.
I hadn't originally intended on purchasing these, but when my cousin Georg heard of them he suggest let's get them, and reproduce in bronze. So We got them! They look great next to my couch. The next step will be to see how to best travel them to Vienna, both cost-effectively and safely. I plan on visiting this December, so one option might be to somehow pack and bring on the plane.
