CANADA - SEPTEMBER 30: Duck! Here comes an aeroplane; Skyscraper focus had to be used by the astonished photographer; who found himself faced with this young giant. Said to be the tallest man on earth; 19-year-old still-growing Robert Wadlow from Illionois; now eight feet seven inches tall; makes his five-foot-elevan father; beside him; look like a miniature. His father; who is also his business manager; has to reach up to put his hand in his son's pocket. The tall boy paid Windsor a visit yesterday; after causing a sensation among customs officials; who nearly had to call on the fire department for an aerial ladder to aid in questioning him.
