Check this out -- side by side comparison of Richard Scarry's The Best Word Book Ever editions from 1963 and 1991. Be sure to read the comments -- some are hysterical! Particularly funny are the comments on the page demonstrating sex change by a simple ribbon.
Thanks to my DH for finding and sharing this gem which he found on bookslut.
By the way, Richard Scarry's Best Storybook Ever (1995) contains original versions of some of these pages. I knew I had seen the 'beautiful screaming lady' recently.
