Mandela had been imprisoned for various things over the years related to his activities to free South Africa, and was released for the last time on February 11, 1990 just a couple of months before this celebration of South Africa's freedom in Oakland. In 1993, he won the Nobel Peace Prize, and on May 10, 1994 he became South Africa's first democratically elected president. It's an incredible story. The passes are in excellent unused condition.
