National Museum of Nature and Science: Great Dinosaur Exhibition Tarbosaurus Tarbosaurus Fossil Version Zero Fighter (Mitsubishi A6M) This is a set of 3 clear files. I bought these clear files at the National Museum of Nature and Science a long time ago when I went to the Great Dinosaur Exhibition. They are new and unused, still in their original plastic. Please check the condition in the images. Approximate size: 18cm x 25cm I think these are rare items that are hard to find nowadays.
