Impressive, to say the least. Being a former WW2 collector, I cannot imagine the time it takes in maintaining the collection. My collection used to take up around 1600-1800 sq ft to properly display, and I thought that was a lot. I'd love to visit the place someday. Be interesting to know if any of the one-of-a-kind items I had ended up there, as the monetary cost of that collection simply boggles my mind.
