These sites have free downloadable (usually pdf files) black and white and sometimes black, white and red pics for Baby.
One or 2 have downloadable ebooks.
Some even have instructions on how to make mobiles out of them, which is a great idea.
And one site shows you where on Amazon.com you can find the baby B/w books.

There’s more to come, I’m still searching.
And I also hope to upload some unusual and obscure pictures to the Infant Stimulation section of the library within a few weeks.
