"Art Brut, Circle Of Dubuffet, 1950s: Abstract Figues Easter Island Moai Statues"
Very interesting work from the 1950s, in the spirit of Jean Dubuffet. On the verso, this oil on canvas laid sdown on isolrel is attributed to Christo Coetzee (1929-2000), an important South African painter who indeed, was in Europe between 1951-59. On the back also, an inscription or title in English "Easter Island, Moai stautues"
