Abstract retailer Original Drawing or Painting gray and orange 8.25" x 10" 1987

My father, Arthur Jacobson (1924 - 2010), was a noted artist and professor (Arizona State University) with a long career and I have his estate of artworks which includes these small oil pastel "sketches" in preparation for larger oil paintings. He handled the medium in a spontaneous and lively way, capturing the clarity and vibrancy of the colors. In his later years, he loved abstract, active shapes and line. This one is an original artwork retailer, untitled (gray and orange) and is oil pastel and charcoal on watercolor paper, made in 1987, 8.25 " h x 10 " w. One of a kind, signed and dated by him.
