These are the forgotten black cowboys who at one point made up 25 per cent of the 35,000 cowboys in the Wild West.
Captured in these black and white photos, the African American cowboys were given all the worst jobs on the trail, had to ride the lamest horses but were banned from brothels because of the colour of their skin.
And despite their huge numbers, they have been largely erased from most popular film and TV depictions of the American West.
Several legendary gunslingers are revealed in the gallery of photos.
