The Sailor Dog, by Margaret Wise Brown, illustrated by Garth Williams, Little Golden Books, 1953.
How can a Little Golden Book that was written by Margaret Wise Brown and illustrated by Garth Williams be anything less than perfect?
Margaret Wise Brown wrote poetry -- not the forced rhythm, attempted rhyming couplets (or quatrains) that so often results in doggerel poetry -- not necessarily with a rhyme at all, but it was poetry none-the-less. Her writing, for the most part, should be read out loud and savored.
I grew up with Garth Williams' illustrations. From the time I was about six, we had all the "Little House" books in our house, and I devoured them. His work shaped the way I thought about illustrations.
