Geometric abstract painting in the Hard-edge style

This unframed square canvas appears to be an acrylic or oil geometric abstract painting. The work features a series of nested geometric shapes centered on a deep blue background. Contained within a black circular void are rotating, overlapping squares in vibrant shades of orange-red, emerald green, and a central blue square with a black inner circle. The composition is stylistically consistent with late 20th-century Hard-edge abstraction or Op Art, emphasizing clean lines and high-contrast color theory. The painting bears a small, dark signature in the lower-right corner that resembles 'Merrick' or 'Marek', though it is not fully legible from the provided photo. The owner identifies this work as being by a Houston-based artist, a claim that remains unverified without further provenance or physical inspection of the verso. The canvas tension appears consistent with contemporary artist materials, and the paint application appears flat with minimal visible impasto. No significant condition issues such as cracking, fading, or physical tears are immediately apparent in the image, though surface dust or minor abrasions are common for exposed canvases of this style.

Based on my visual analysis of the provided image, this work is a square, unframed geometric abstract painting in the Hard-edge style. The composition features nested shapes on a deep blue ground and bears a signature in the lower-right corner that appears consistent with 'Merrick' or 'Marek.' Per user submission, the work is attributed to a Houston-based artist. From what I can see, the paint application is flat with minimal impasto, typical of late 20th-century acrylic or oil abstraction. I cannot verify the medium, support, or specific authorship from a photo alone; a physical inspection of the verso (back of the canvas) for gallery labels or artist notations would be necessary to establish provenance. The estimated value of $600 to $1,200 assumes the attribution to a regional professional artist is correct and reflects the current market demand for mid-to-late 20th-century Op Art-influenced works. However, this estimate is a hypothesis based on unverified information. The value depends entirely on formal authentication; should the work be identified as a student piece, a decorative reproduction, or by an unknown amateur, the value would likely fall to a decorative range of $100 to $200. Conversely, if research into the signature confirms a highly collected regional master, the value could exceed this range. To confirm this estimate, I would recommend an in-person examination by a specialist to verify the age of the materials and a search of regional exhibition records. The absence of a frame and any potential surface abrasions, which I cannot fully assess from the image, are also factored into this conservative range. General market interest in bold, geometric abstraction remains stable for interior design purposes.
