Richard Scary’s The Best Word Book Ever is a childhood classic. But as culture and political correctness change, so must the book. A guy went through his own 1963 version, page by page, noting the differences between the 1991 version of his kids and sharing side by side photos in a Flickr set. The changes are pretty much what you expect; adding a female character in a few places and including the father character in more family activities. My favorite is the airline scene which featured a “pretty stewardess” and “handsome pilot” in 1963.
Apparently the airlines were wild and crazy in the 1960’s.
