North American Airlines Brochure, Page 5

Back cover of advertising brochure and timetable issued by North American Airlines, circa 1955. This airline existed from 1950 to 1957.  In 1956, North American Airlines was forced to change its name after a court proceeding found that use of the name "North American" had created "substantial public confusion" with American Airlines and constituted unfair competition.  The company was prohibited from using "North American Airlines" or any combination that included the word "American."  The company changed its name to Trans American in 1956 and ceased operations in 1957.
