Pierre Bonnard, The Terrace at Vernonnet, 1939. Oil on canvas, 58" x 77"
Bonnard never tried his hand at abstraction, but helped himself to the motifs one might find in European abstract painting after Cubism and Mondrian. Look at the grid structure of this picture, built with blocks of complementary yellow and violet. I've seen this picture at the Met a hundred times and never tire of it.
