Oil painting signed 'O.B. 85-'

This is an unframed or simply framed oil painting on canvas depicting a rural agricultural scene. The composition features a farmer guiding two horses as they pull a plow through an earthen field in the foreground. The midground shows a rolling landscape with harvested grain fields, stacked sheaves of wheat, scattered small houses or barns, and sparse green trees under an overcast, grey-green sky. The palette consists primarily of earthy tones including greens, browns, muted yellows, and grays, applied with visible brushstrokes. In the lower right corner, there is a visible signature and date painted directly onto the canvas reading 'O.B. 85-'. The owner attributes this work to artist Onerva Borg with the title 'Ploughing with Horses' and a date of 1985, measuring approximately 75x55x3 cm; however, this user-supplied attribution is entirely unverified by physical inspection. The physical condition appears generally stable with minor surface dust, consistent with a late 20th-century amateur or regional artwork. The attribution in the name rests purely on the observation of the legible monogram signature at the lower right. The work is unauthenticated.

Based on the provided image and information, the owner identifies this work as an oil on canvas titled 'Ploughing with Horses', dated 1985, and bearing a monogram signature 'O.B.', pointing toward artist Onerva Borg. Based on what I can see, the painting features a rustic agricultural composition rendered in earthy tones with visible brushstrokes, and bears a signature in the lower right corner consistent with the owner's reading. However, I can't verify from a photo whether the signature is contemporary to the work or if the attribution to Onerva Borg is correct, as visual inspection and physical analysis would be needed to confirm these details. Assuming the attribution is correct, regional landscape oil paintings of this scale and period typically trade within the $300 to $600 range in the secondary market, driven by moderate demand for late 20th-century European regional art. If the piece turns out to be an unattributed work, a copy, or created 'in the style of' rather than an autograph work by the named artist, the value would likely decrease to a decorative range of $100 to $250. To establish a higher degree of certainty regarding authorship and value, physical examination by a qualified fine art expert, a review of provenance documentation, and potentially technical analysis of the canvas and pigments would be necessary.
