Cubic collage - Version 4Although this illustration may look like a painting or drawing, it’s actually a reproduction of a collage. A collage is a composite, or collection, of shapes that have been glued to a flat surface. Some artists who constructed collages based much of their art on the shapes created from a perspective drawing of a cube or other geometric solid. This was called Cubism, a style of painting and sculpture developed in the early 20th century that reduced natural forms to their geometric equivalent. It was often influenced by African Art.
