Original painting, oil on board, in the abstracted landscape tradition associated with mid-century palette-knife painters such as Nicolas de Staël. Thick, faceted planes of burnt orange, ochre, deep teal, and green are built up around a dark blue-and-white central aperture suggesting a cave mouth, a mountain gorge, or a pool glimpsed between rock faces. The heavy outlines and sculptural paint texture evoke the dramatic, post-war expressionist styles of mid-20th-century modernist painters. Unsigned; artist unidentified. Board measures 16" x 12" (unframed), oil, heavy impasto. A richly textured, painterly landscape abstraction suited to a collector of mid-century modernist or knife-painted work. Good vintage condition with light craquelure and surface wear consistent with age; please review photos closely as part of the description.
