From the picture I assumed that the white background has been faded to a sort of yellow due to aging or because it has been displayed in a shop-window and suffered from sunlight.
In fact this area and the decals are covered with brown mold. The top of the box is also a bit bent to the inside and I had to fill up the box with paper to make it flat.
Thus the kit is not in "excellent used" condition as praised.
I would have appreciated to have such infos available in the advertisment of this kit.
