Zip! Blam! Zowie!
Meet Ward Jenkins.
Ward's an animation director in Atlanta, Georgia who happens to have a blog called The Ward-O-Matic which, as the name may have indicated, sometimes dips into his vast collection of old timey-books. On this site you'll occasionally stumble upon such beauts as Cape Canaveral, written and illustrated by M. Sasek (1963) or The Day the Cow Sneezed, written and illustrated by James Flora (1957) which is absolutely groovy. Apparently Mr. Jenkins worked with Flora's biographer, Irwin Chusid on the post and Mr. Chusid supplied the blogger with some great mock-ups of several page spreads from the book. This title, oh sweet publishers who read me, is out of print and the time has NEVER BEEN BETTER to bring it back. You have been alerted.
I'm saving the best for last, though. Take into consideration the Flickr page Retro Kid. The site states:
I'm interested in anything associated with illustrated children's books from the mid-1940's through the mid-1960's, give or take a few years. As long as it has that cool mid-century modern styling that was so popular during that time. Some of what I dig are books and anything illustrated by Mary Blair, JP Miller, The Provensen's, Art Seiden, Aurelius Battaglia, and the like. I'm not limiting to just these illustrators, but willing to be open to just about anything similar.Plenty of goodies there for anyone with a yen for the past. True hep-cat stuff.
