Jim Flora (1914-1998), who was best known for his funky, colorful and lively album art in the 40s and 50s apparently did children's books... or at least one.
stumbled upon this one drawing by complete accident and clicked on it, as I usually do when I find something I really love.
When I looked at some more of the art I was really intrigued. Then I read that the illustrator was "James Flora," also known as Jim Flora. Sweet! Grandpa's Ghost Stories was created in 1978. I'm going to see if I can score myself a copy somewhere. I'll keep you all updated.
