Illustrator of The Silver Robin Illustrated Litttle Black Sambo in 1927

The Illustrator of The Silver Robin, a book from Washington School Library that I read over and over again, also illustrated Little Black Sambo in 1927.  Frank Dobias was one of a number of illustrators of this story.  According to the internet, the Frank Dobias illustrated version of Little Black Sambo was a best-seller in Japan.  The book appears on the internet at this time, and is viewable.  I am at this time reading The Silver Robin - I remember liking the story and realize the illustrations were favorites of mine as well.
