One of two American athletes famed for making a Black Power salute at 1968 Olympics is selling the gold medal he won in Mexico City.
Tommie Smith, who performed the black-gloved protest with fellow American John Carlos after the 200 metres at the Games, is selling his gold medal and the track shoes he wore in the race.
Their gesture against racial discrimination sparked outrage in the Olympic movement and the two were sent home from the Games.
But their protest has since come to be seen as an iconic gesture of solidarity.
The bidding for Smith's memorabilia starts at $325,000.
