Signed Mountain River Landscape Oil Painting

This is a horizontal landscape oil painting on board or canvas, depicting a tranquil river winding through a mountainous valley. The composition features a blue-green waterway in the foreground flowing between rocky banks, leadings the viewer's eye toward a prominent peak in the background. The color palette is dominated by autumnal and earthy tones, including deep browns, ochre, and dark greens for the foliage, contrasted against a hazy, pale yellow and teal sky. The paint application appears somewhat thick, with visible texture in the sky and water. The piece is signed in the lower right corner with what appears to be the name 'J. DERDEVEN' or similar lettering in block capitals. The painting is housed in a contemporary recessed wooden frame with a wide profile, finished in a light oak veneer with a visible grain pattern and a gold-toned inner fillet. The frame shows minor signs of handling, including a price sticker in the top left corner. The style and framing suggest a mid-to-late 20th-century production, likely mid-century original decorative art. The overall condition appears stable with no major flaking or visible restoration, though some yellowing of the varnish may be present, common for pieces of this age.
