According to Google..."It is in Washington, D.C. The was founded in 1888 and by a nonprofit corporation, the Society. The society originally intended the periodical to be oriented toward the United States, but the nature of its articles soon made it a with a world view." I graduated in 1987!! LOL
Thanks for the flip! That car page you were talking about in the second magazine was during WWII. The American government took American citizens of Japanese decent and put them in camps for many years. It's an awful part of American history that not many people know about or acknowledge!
The content might be the same but those were definitely made for a European market. The car ads give it away; they're all models that weren't sold in the U.S.
There was a time long before the invention of Google and Wikipedia, when these National Geographic magazines were very useful for the procurement of knowledge and information. I've heard that many people in India were helped a lot by these in their civil and administrative service examinations. Do you have the June 1991 issue? Its cover story was about pollution in the eastern European countries which had been recently released from decades of communist rule. The cover featured two young boys who were blackened by the smoke and wastes given away by a local factory in a small Romanian village.
