I have every copy of National Geographic from 1960 to 1990 available for sale.
If there's any you're interested in, please feel free to just make me an offer and a copy you would like.
They are nearly all in mint condition, and there are many special editions, and limited edition maps.
I'm based in London, so everything will be posted by Recorded Royal Mail. If you are outside of the country we can arrange an additional fee for couriers.
