Associated Names

Artist, American, born 1937

The image shows intersecting lines forming triangular shapes against a brown background. The lines create an abstract composition with angles converging towards a vanishing point. This geometric abstraction suggests simplicity and symmetry, similar to origami or folded paper art.
