Wow, that is a tough question. I can't think of any sources off hand. I am guessing you have reviewed the wide variety of bungalow style homes books?? If not, check out your public library and your local big bookstore...
a dealer here in louisville has a very nice period linoleum area floor covering with childrens stories on it. i have never unrolled to see exactly what it is.
The best children's rooms for me, personally, are those that have a pastel theme and with walls that allow your kids to doodle (and erase, of course) as they grow up. Those are just cute! My nephew's room is so adorable (wish I took a picture!) but because my cousin worked the room in a way where it's always a work in progress (stickers instead of paint), my nephew gets to contribute ideas for his room. A dream, if you ask me!
In our previous house there was half of a children's linoleum "rug" in the attic. After our first daughter was born I cut it down, and glued it to a masonite board. Here is a picture of it mounted on her wall.
Take a look at my daughters' bedroom in the Finish Pictures of my Photo Gallery at {sorry no self promotion links} I tried to stay true to the Craftsman feel with the exposed beams, mahogany and ebony picture rails, etc.
