"...and Owl tried to sleep."

I recently came across Pat Hutchin's picture book, "Good-Night, Owl" (1972) about an owl who just can't get a wink of sleep because of all the racket those other birds make during the day. I know Hutchin's "Rosie's Walk," but I have never read seen this book before and it was a joy to discover. I love the rich royal blue and gold on the hardcover edition, but don't the books illustrations seem to be influenced by the patterns as well as colors (the oranges and yellows) of traditional Russian folk art? Maybe just a little.
