It is the National Museum of Denmark (suffix "dk"). They will not sell directly over the net, but if you send them your postal address will send you a pro forma invoice which you then fill out and return. You may pay with a US credit card, which usually yields a better exchange rate than you can get for direct currency exchange. The 330 kronor price does not include shipping, which I think is another 140 Kronor. The last time I exchanged for Danish kronor it was just a fraction under 7 kronor to the dollar.
