Hiroshi Matsumoto. Unlike those extreme large-sized ones, these small 9×9 painting, are intriguingly less common in abstract artwork. No other abstract artists have done it so passionately than this oil painter from Kobe city in Japan. His style of paintings characterized with bold brush strokes just fit into small canvas. Using oil medium laid on thick plaster, ever creamier than cake frosting. Presentation is a fusion of minimalism and simplicity.
