"Pierre Brassau" was in fact a four-year-old common chimpanzee named Peter from Sweden's Borås djurpark zoo.[2] Axelsson had persuaded Peter's 17-year-old keeper to give the chimpanzee a brush and paint. After Peter had created several paintings, Axelsson chose the best four and arranged to have them exhibited at the Gallerie Christinae in Göteborg, Sweden.[1] Critics praised the works, with Rolf Anderberg of the Göteborgs-Posten writing, "Brassau paints with powerful strokes, but also with clear determination. His brush strokes twist with furious fastidiousness.
