WESTON — South African contemporary art, long one of the nation’s best-kept secrets hidden from the world by a long cultural boycott, is beginning to enter the international art circuit. On Sunday, September 17, at 3 pm, Martha and Hugh Scott will present a slide-lecture concerning such art using images during their recent venture into South Africa. The program will be open to the public free of charge and presented at Weston Library, 56 Norfield Road. Call 203/222-2656 for details.
