Leaf, from Chicago but living in New York City, creates abstract paintings with a story. These pieces are another part of the artist's work, kinetic sculptures. The pieces here fall into that category. The scroll obviously suggests motion (and may, be capable of motion).
Leaf was born in 1929 and attended the Institute of Design (once known as the New Bauhaus) and later received a B.A. in Art Education from Roosevelt University and an M.A. from in Art Education at Institute of Design.
