My favorite picture book edition of Edward Lear's The Owl and the Pussycat is, not suprisingly, James Marshall's. I love that the "beautiful pea-green boat" is a cruise ship, the S.S. Dorabella. The watercolor sketches for this book were Marshall's last work.
Lear himself did not finish "The Children of the Owl and the Pussycat," portions of which were published posthumously. Here are the opening lines:
Our mother was the Pussycat,
our father was the Owl,
And so we're partly little beasts
and partly little fowl.
The brothers of our family
have feathers and they hoot,
While all the sisters dress in fur
and have long tails to boot.
We all believe that little mice,
For food are singularly nice.
