Rapunzel by Barbara Rogasky and illustrated by the late, great Trina Schart Hyman is another of my top Rapunzel picture book favorites. Unfortunately, since Hyman's untimely death to cancer, her books are starting to go out of print, as is this one. Hyman had a highly romantic flavor and yet realistic tone to her illustrations which works especially well with Rapunzel. Fortunately, the internet (and many libraries) make it possible to see this anyway.
Here are a few more illustrations:
I'm so glad I own this one...it is just as lovely as Zelinsky's but completely different.
