Geometric abstract oil or acrylic painting bearing the signature "Rene"

This is a rectangular vertical-format painting featuring an architectural geometric composition. The artwork is composed of interlocking, open rectangular frames and three-dimensional block-like structures depicted in a monochromatic palette of blues, ranging from pale cyan to deep navy and slate grey. The background is a flat, light blue-grey tone. Structurally, the painting uses hard-edge techniques and forced perspective to create an illusion of depth and impossible architectural space. In the lower right-hand corner, the work bears a cursive signature reading "Rene" in dark blue paint. Per the owner's notes, the work is attributed to an artist named Rene, though this attribution remains a hypothesis subject to in-person verification. The style is consistent with mid-to-late 20th-century geometric abstraction or Op Art influences. The painting is housed in a simple, dark brown wooden frame. Observed condition includes slight surface variations consistent with age and what appears to be minor scuffing or dust accumulation along the lower edge of the canvas. The physical texture suggests either oil or acrylic on canvas, though the medium cannot be confirmed from the image alone.

Based on the provided image, I have examined this vertical-format geometric abstraction featuring interlocking blue and grey architectural forms. The work bears a cursive signature in the lower right corner reading 'Rene'. Per the owner's submission, the painting is attributed to an artist named Rene; however, this attribution remains a hypothesis that I cannot verify from a photograph alone. The style and hard-edge technique are consistent with mid-to-late 20th-century Op Art or architectural abstraction. The value estimate of $600 - $1,200 is based on the assumption that the attribution to a listed artist named 'Rene' is accurate and that the work is a period production from the mid-20th century. Factors favoring this value include the strong visual composition and the popular monochromatic palette which remains sought after in the secondary market for interior decor. However, I cannot confirm the medium as oil or acrylic, nor can I verify the age of the canvas or stretchers without a physical inspection. The condition appears fair with visible surface dust and minor scuffing. To confirm the identity of the artist and the work's origin, an in-person examination by a specialist is required, alongside a review of provenance or exhibition history. If this work is determined to be an unsigned decorative piece 'in the style of' or if the signature cannot be linked to a known professional artist, the fair market value would likely decrease to a decorative range of $150 - $300. Market demand for geometric abstractions is generally stable, but values are highly dependent on the formal verification of the creator’s identity.
