A great sketch of a frog by Swiss animal expert Fritz Hug. I love frogs. Their arms and legs always remind me of human anatomy. (Part of the reason I could never eat them.)
Below are beautiful sketches by Disney's Bernard Garbutt. What amazing observation.
Perhaps a dose of this kind of body structure might have helped the frog characters in Disney's The Princess and the Frog, one of the studio's last hand drawn films .
