Richard Scarry's Best Word Book Ever, 1963 to 1991
Hi everyone! Here's the link I mentioned a couple of weeks ago to someone's set on flickr.com on the changes in Richard Scarry's Best Word Book Ever from 1964 to 1991. If you click on the thumbnails on the right, you can see several page-to-page comparisons. The person who posted it even made a lot of notes you can mouse-over within the pictures, annotating the specific changes.
Some changes shown on just the cover (http://www.flickr.com/photos/kokogiak/66087367/in/set-1425737/) include a dad inserted into the kitchen and a 'policeman' changed into a "female officer."
