Superman turns up in the strangest places.

I found this 13-page book at the library the other day. It's part of the "I Know Opposites" series of books, published by Weekly Reader Books. Obviously aimed at very young children, it's an educational book showing an image and short phrase on each page, noting whether the thing depicted is alive or not alive.

For example, a photograph of a grizzly bear on one page has the short, declarative sentence below it reading, "The bear in alive." On the facng page, there's a photo of a teddy bear, and the sentence "The toy bear is not alive."

Where does Superman come in...?

Perhaps...but I wouldn't tell Grant Morrison that.
