The Illustrated Manuscript, though not Illustrated with Examples

I've just stumbled on to your blog and I'm really enjoying it. Thank you. I have a question: What does an illustrated children's book manuscript actually look like? I'm trying to picture it, but it's hard considering there aren't yet illustrations.

If you mean a manuscript that is meant to be illustrated by someone other than the author, it looks like a manuscript. It's up to the editor reading it to picture what would be going on in the art.

If you mean one of the manuscripts I get that's already illustrated, that varies a great deal. Simple pencil sketches, full-color art samples (photocopies, one hopes), the occasional manuscript with illustrations borrowed from someone else's book (instant reject) ....
Unless the author is a professional artist, including art of any kind is often a bad idea. See my previous post "Stick Figure Theater."

Is it possible to view actual manuscript submissions (strong ones vs. poor submissions)?

Is it possible for me to post submissions I get at work on my personal blog? Hell no. Those people sent their manuscripts to a publisher, who can be relied upon not to use their intellectual property in any way they do not explicitly agree to.
