Peter Snell was the best 800/1500 runner in the world in the early 1960s. The bookends of his career were the 1960 and 1964 Olympic Games. Snell won Olympic gold in 1960 at 1500m and then doubled by winning both the 800m and 1500m in 1964 - one of the rarest feats in track and field history.

Snell set a total of five individual world records and was part of New Zealand's 4 x one mile world record setting relay team.

Poland's Irena Szewinska dominated sprinting in the 1960s and the 1970s. She won 7 Olympic medals, including three gold, two silver, and two bronze. She won 10 medals in the European Championships, including 5 gold, 1 silver, and 4 bronze.

Szewinska is the only person to set world records at 100m, 200m, and 400m. In addition, she is a barrier-breaker, as she was the first woman to break 50 seconds at 400m.

Wyomia Tyus was the first athlete ever to repeat as Olympic 100m champion; she won gold in 1964 and 1968. She added a third gold as she anchored the '68 4x100m relay to a world record. She also tied and set the world record in the 100m and set a total of 6 world records in her career.  

Tyus attended Tennessee State University and was one of the Tigerbelles in Coach Ed Temple's legendary program. At the 1968 Olympic Games, Tyus supported the Olympic Project for Human Rights by wearing black shorts instead of the team-issued white ones. 

Note: It is utterly remarkable to have the autographs of these three legends - three of the greatest ever to compete in track and field - on the same page. Phenomenal.
