Mid-century modern style mixed media resin and wood wall art

This rectangular wall hanging is an example of mixed media assemblage, stylistically consistent with the brutalist and experimental craft movements of the 1960s and 1970s. The piece features a central geometric starburst or 'sunburst' motif constructed from thin, cross-hatched wood splinters or bamboo-like strips. These elements are set against a background of amber-toned resin and textured surfaces that suggest a radial, brushed pattern emanating from the center. Visible inclusions include chunks of green pulverized glass or slag, along with darker brown stones or glass fragments scattered around the perimeter. The entire composition is encased or coated in a thick, gloss resin that provides a high-shine, protective finish. The corners are accented with gold-toned metallic leaf or paint, showing some minor wear and edge chips. No visible signature or maker's mark is discernible in the image; consequently, this is attributed based on its craft-heavy aesthetic typical of 20th-century decorative wall plaques. The construction shows signs of hand-assembly, including slightly uneven resin levels and manually placed natural materials. Condition appears fair, with visible surface dust and some irregularities in the resin coating that are typical for aged mixed media pieces.

Based on the visual evidence provided, I have evaluated this rectangular mixed media wall hanging. I am treating the attribution as a hypothesis consistent with 1960s-1970s amateur or professional boutique craft movements, possibly influenced by the aesthetics of William Lawrence or similar brutalist-era designers. From the photo, I can see characteristic use of amber resin, cross-hatched wood elements, and glass inclusions. However, I cannot verify the structural integrity of the resin or the presence of a hidden maker's mark without a physical inspection. The value range of $150 to $350 assumes the piece is an unattributed mid-century decorative work in fair condition. This market is currently driven by the demand for 'Brutalist' and 'Boho-chic' interior decor. If this piece were to be linked to a known studio or designer through documentation or a discovered signature, the value could increase significantly, potentially reaching $600 or more. Conversely, if physical inspection reveals the resin is unstable or that it is a much later mass-produced 'in the style of' reproduction using synthetic shortcuts, the value would likely drop below $75. To confirm the nature of this item, an in-person examination is necessary to assess the weight, the specific type of resin, and the age of the wood oxidation. Provenance documentation or a label on the reverse would be required to elevate this from a 'decorative object' to a 'designer-attributed work.' Given the visible surface wear and edge chips, the current estimate reflects its status as an attractive period piece with some conditional issues typical for its hypothesized age.
