This was an illustration for some kid's book by River Bend Publishing (or something like that.) I made it about 15 years ago. According to the deal I was supposed to get a copy of the book but never did. I'm finding out that's standard practice when there's nothing in it for them to send a copy.
The drawing is a cutaway view of a farm house with a big family doing whatever they're doing. I like to think this house has been through an earthquake or a tornado, and the roof was destroyed, but the dad was so lazy he just left it.
