This is an old book. As a matter of fact, it is nearly as old as me. The publishing information says, "First Issued 1930, New Edition (Illustrated) 1946."
I'm sure I have the 1946 edition as mine is illustrated with many amazing white on black illustrations by Nora Lavrin.
I take inspiration from the illustrations and if I illustrate, I will continue with the white and black.
Something that might be of interest is (I think) Nora Lavrin's illustrations are a method called "dry points" which will of course explain why, I will not be able to actually make my illustrations like hers by just using my white gel pen on black.
PS: I'm watching for characters in my dream images. It's happened before.
