I am looking for a children’s book.

This book was published around 1959-1960 give or take a year or two. It had a medium blue hard cover and was approximately 8 x 6 and 100 pages give or take some.

It had many short stories and poems. The illustrations were primarily black ink and the drawings remind me of Irene Haas illustrations. This book may have been part of a Harper and Brothers adult book club selection because I have another book my mother had from this club and it is titled “The Day Christ Was Born” By Jim Bishop. She said the children’s book was offered as a special selection. My sister recalls the word “Willow” she thought maybe that may have been in the title of the book or possibly a title to one of the stories. I have been looking for this book for quite a few years and any help would be appreciated.
