This poster was made to protest the tour of the national South African cricket team, who were due to come to Britain in the summer of 1970. The tour was cancelled due to the widespread protests and demonstrations, led by the Anti-Apartheid Movement (AAM) and Stop of the Seventy Tour campaign.
The AAM was a British-based protest group founded in the 1959. Members led campaigns to raise awareness of the apartheid regime in South Africa, put pressure on the government to introduce economic sanctions, boycott South African products and events, free Nelson Mandela from prison, and more.
