I had a great aunt that had a mess of Nat. Georaphics from the late 50’s and early 60’s at her lake cabin. When I was a kid, I used to love to sit and read those things when it was rainy or while we were waiting to go swimming (”Not for a half-hour after you eat!”).
She had an issue that highlighted the USS Nautilus’ first trek under the Arctic ice, being the 1st submarine to go under the North Pole.
She had an issue that highlighted the maiden voyage of the USS Savannah, what was then the world’s first nuclear-powered frieghter.
I also remember all the ads for cruises, not just for exotic vacations, but also for regular runs across the North Atlantic.
Back then, we still lived in a ‘age of wonder’.
(BTW...she let me have a bunch of those old magazines, but alas...over the years they’ve been lost to the mists of time.)
I think I spent most of my time reading the issues that had stories about native African tribes...
