Roswell UFO incident
In 1946, Harold M. Sherman published a pulp science fiction book entitled "The Green Man: A Visitor From Space". The cover illustration was of a normal-looking and proportioned human being, albeit with a green skin. Nationally syndicated columns by humorist Hal Boyle spoke of a green man from Mars in his flying saucer in early July 1947 during the height of the brand new flying saucer phenomenon in the U.S. that started June 24 after Kenneth Arnold's famous sighting and the Roswell UFO incident. However, Boyle did not describe his green Martian as "small".
