Original unsigned oil painting on paper, mid-20th century, most likely 1940s, in the cubist tradition. The work features a dynamic, geometric network of intersecting linear struts, architectural scaffolding, and faceted planes that suggest a modern cityscape or industrial superstructure. The artist uses thick, impastoed paint application over textured ground with a palette of cerulean blue, yellow, crimson, rose, and charcoal gray against a pale off-white ground. The structural composition carries strong influence from American Precisionism, Russian Constructivism, and post-cubist architectural abstraction of the 1940s. Executed in oil on paper, unframed, measuring 12" x 18". Vintage condition with clear age-appropriate wear to the paper support. Features visible paper edge losses, small tears along the margins, creasing, and corner wear along the unpainted paper border. The painted area itself displays rich texture and strong paint adhesion. Unframed; ideal candidate for conservation matting and framing to protect the delicate paper edges. Please inspect all high-resolution photos carefully to evaluate edge condition and paper aging prior to purchase. An energetic, linear composition suited to a collector of cubist or constructivist-influenced work who doesn't mind restoring/conserving a genuine vintage piece.
