This is the classic children's book,
Goodenough Gismo, by Richmond I. Kelsey, published in 1948. Nearly unavailable in libraries and the collector's market, it is posted here with love as an "orphan work" so that it may be seen and appreciated -- and perhaps even republished, as it deserves to be.
After you read this book, it won't surprise you to learn that Richmond Irwin Kelsey (1905-1987) was
an accomplished artist, or that as
Dick Kelsey, he was one of the great Disney art directors, breaking your heart with "Pinocchio," "Dumbo," and "Bambi."
