Collection of Ronald Ahlström Abstract Mixed Media Compositions on Boards: A collection of three abstract mixed media collages on boards by listed American artist Ronald Ahlström (1922-2012). Composed of acrylic paint, ink, various paper scraps, and other materials, these compositions feature abstract geometric designs of jagged shapes and delineations. The largest composition on foam board includes red, blue, and yellow rectilinear shapes scattered throughout a surface covered with vibrant pigments in black, blue, green, and pink. All works are signed to the front and to the verso; all versos include additional handwritten information about the composition. Each work remains unframed.
