1950s Illustrations by Sunny B. Cook

This book I bought at a thrift store some years back. I like the classic 1950s style that the drawings have.

I don't know anything about the illustrator other than her name  - Sunny B. Cook (at first I thought it was a man's name, but Mr. Sung kindly told me otherwise - see comments;). In Danish the book is called "Der var engang en lille dreng" ("There Was Once a Little Boy" written by Blossom Budney). It was originally published in 1956.
