I'm looking for a children's book from the 1960's or before that is
shaped like a mouse or a mouse's head.  My husband (born in 1965)
remembers this book very fondly and I would love to find it for him
but have done much searching and not turned up anything.  He thinks it
might have been a version of The Country Mouse and City Mouse.  He
feels it was shaped like a Mouse Head but may have been shaped like a
whole mouse.
