A while back, I was browsing some stores when I found a stack of old National Geographic magazines. I find old magazines incredibly interesting. Everything is still perfectly preserved from when they were first published. We get to see photos and read articles exactly as they were fifty or more years ago. There aren't a ton of things out there like it.
Here are some scans from the July 1955 issue of National Geographic.
I especially liked this ad for telephone booths.
