Oil painting of a Mediterranean street scene, signed illegibly

This is an original oil painting on a stretched canvas depicting a sunlit Mediterranean courtyard or street scene. The composition features tall, warm-toned yellow and tan buildings flanking a paved square, with a prominent dark green tree in the center dominating the midground. To the lower right, a small green boat or structure is draped with fabric or netting featuring striped patterns in white, red, and blue. The brushwork is expressive and impasto-heavy, utilizing a palette of ochres, blues, greens, and earthy browns to convey strong sunlight and deep shadows. The canvas shows minor signs of age, including slight edge fraying and surface dust consistent with a mid-20th-century or later amateur or regional artwork. At the lower left corner, there is a visible signature and date that appear worn or partially obscured, reading roughly as '...1976'. There are no other visible maker's marks or stamps on the front. The attribution rests entirely on the stylistic characteristics of the brushwork and the presence of the lower-left signature, which remains unverified as to the specific artist.

Based on what I can see in the photograph, this oil painting depicts a sunlit Mediterranean street scene with expressive, impasto-heavy brushwork and bears an illegible signature alongside a date of 1976 at the lower left. The canvas shows minor edge fraying and surface dust consistent with mid-20th-century regional or amateur artwork. I can't verify from a photo whether the materials or signature are period-correct, and physical inspection would be needed to confirm the medium's exact age and condition. My valuation of $300-$500 assumes that the piece is a mid-century regional oil painting of this specific style and quality. General market demand for unverified or regional decorative mid-century European street scenes is modest, typically driven by decorative appeal rather than collector investment. Should this piece turn out to be a modern reproduction, a later copy, or merely created in the style of a regional painter rather than a period work from 1976, the value would likely decrease to the $100-$200 range, reflecting strictly decorative value. To better understand this piece, what would be needed to clarify its status includes an in-person physical examination by a fine art specialist, detailed provenance documentation, and careful analysis of the canvas weave, pigments, and signature under magnification.
