Wednesday's sale outperformed two longtime leaders in South African art at auction, Peppiatt said, citing "Landscape Stellenbosch" by Jacob Hendrik Pieerneef sold for 713, 250 pounds, and Irma Stern's "Congolese Beauty" for 541, 250 pounds.
Founded by Dr Anton Rupert, a tobacco billionaire, conservationist and critic of apartheid who was born in Graaff-Reinet in 1916, the museum is housed in a beautifully restored early 19th-century mission church, with mostly expressionistic and abstract canvases by South African artists, including IrmaStern and Maud Sumner.
