The listing, Unused US National Parks stamps from 1930s has ended.
A group of unused US National Parks from the 1930s as shown. The stamps are unused with original gum on the backs and not hinged. However many of them have some light creases in the gum on the backs, see closeup of the Zion pair showing some diagonal gum creases. In a few stamps these creases show up on the front, light and hard to see on the Zion, they are most visible on the blue Crater Lake. Most of the stamps appear very nice from the front.
