That is a very awesome lamp. I saw one that was almost identical to it at the ReStore 'Habitat for Humanity' shop in Rockwall, Texas about a year ago. Unfortunately,, when I found it, I was in my car so I couldn't buy it. It was gone when I went back to get it with my truck. The only difference between the two was the map (the one I saw had a continental map instead of the ocean currents).
That's rather disappointing, but encouraging to know that these were apparently not just custom built for the space but must have been purchased from someplace. It does make me wonder if these beautiful pieces are still available.
I understand... when I found the one that I found, I was so excited thinking that it was one of a kind. I was so disappointed that it was gone when I went back to purchase it. However, at least I now know that there are others out there that are similar.
