In the later 1960s Jackson made a series of square paintings that included figurative elements from newspaper photos of the Sharpeville Massacre of March 1960 in South Africa. At that time, he also carved a wood block and made one print on paper, which was discovered last year. Using that print as a matrix, he was able to reproduce the woodblock on canvas in an edition of four, and has hand colored this one print. The “Sharpeville Series” continued in the 1970s with a number of large canvases based on the same figurative forms seen in the photographs of the event.
