Jo Mora did many of these humorous illustrations for the National Parks and other tourist destinations. This one includes a map of the Grand Canyon and is punctuated with his delightful and funny drawings of people and animals. This poster was printed by Jo Mora Publications, Monterey Ca. It was originally done in 1931. This is an original, and was purchased by me from Jo Mora's son about 40 years ago. At the time, he was still selling some of his father's originals. It is in good shape and measures 19" x 15". One only.
