We just learned about the famous work of art Houses at L'Estaque by French painter Georges Braque.
Another famous work of art is the painting Houses at Fruit Dish on a Checkered Tablecloth by Spanish painter Juan Gris in 1917.
Juan Gris's painting is a part of the Cubism style of Abstract Art, where the painter liked to use lines and triangles to try to show a different side of a picture, making it look very strange, but still very interesting.
