Former president Nelson Mandela’s Houghton, Johannesburg, office was flooded with 20000 postcards and letters on Wednesday from South Africans wishing him well for his retirement. The SA Post Office launched a campaign after Mandela retired from active politics in June, to give the public the opportunity to express their sentiments to him. Postman Johannes Lombard pedalled in on a trademark red bicycle to hand Madiba an additional wad of fan mail. Mandela also invited Lombard, stationed at the Yeoville depot and who has been a pedal-pushing postman for 33 years, to attend a braaivleis with him. The bulk of the massive mail delivery was from children.
