Well, someone was kind enough to drop me an email on the matter:
I think it's from another book, about a baby bunny who wants to go be various things independently, and its mother says it will be something associated whatever thay are -- e.g., baby will be a fish, so mother will catch the fish; baby will be a sailboat, so mother will be the wind; that sort of thing. I can't recall the title at the moment, and I may be wrong about the fish/fishing thing being in it, but I think that's the case.This sounded familiar, and a little Googling pointed me to "The Runaway Bunny," which was written and illustrated by the same people who did "Goodnight Moon." So what I mistook for a wacky picture was simply some clever cross-promotion...
