Lot of 18 National Geographic Maps (1980s)

Fun collection of 18 National Geographic Maps mostly from the 1980s. Condition is not perfect (see Soviet Union photo) but nothing is trashed. Good for collectors, classrooms, or just a slice of the world as it was. Selling as a lot but if you want a picture of a specific map let me know. Thanks for looking. Reasonable offers and bundles always welcome.
