I've looked for this also in the past. Found nothing. Very frustrating for me. Search and see if there are any pdf copies lying around anywhere. I've also been able to buy rare books and take them to printer buddies of mine who have professional machines to scan this stuff. The latest one I did was Animal bedtime Stories, which are awesome and a favorite of mine when I was a kid. If anyone wants a copy, let me know. Beautiful stories and beautiful illustrations.
