We believe that the photo must have been taken on or around 27 April 1994 and shows ANC supporters celebrating their right to vote, their release into freedom, and the imminent victory of their political party.
The ANC is today still South Africa's ruling party, with Thabo Mbeki, successor to Nelson Mandela, at the country's helm.
If anybody knows who may have taken this photograph, please post a comment so that we can credit them.
