Fewest Mr Olympia contestants

In 1968 Sergio Oliva (USA), known as 'The Myth', defended his Mr Olympia title unopposed at the Brooklyn Academy of Music, New York City, USA. In Paris, France, Arnold Schwarzenegger (Austria) was also unopposed in 1971. Oliva and Schwarzenegger had a series of epic battles for the title between 1969 and 1972. Oliva won three times, from 1967 to 1969, but the 1969 title was a close run. Schwarzenegger won the 1970 and 1972 titles, edging Oliva into second place both times.
