Mixed-media industrial diorama in the style of brutalist metal art

This item appears to be a small-scale, mixed-media sculpture mounted on a live-edge wooden base. The central subject is an abstract representation of industrial machinery, featuring elements consistent with an oil well pump jack, associated tanks, and a vehicular tractor. The construction appears to involve soldered or welded rods and sheet metal, possibly brass, copper, or steel, showing a varied brown and gold-toned patina. The wooden base exhibits a rough-hewn texture with visible wood grain and natural edge characteristics. On the lower right corner of the wood, there is a handwritten signature that appears to read 'Stover Fox' or similar, which may indicate the creator, though this attribution remains a hypothesis without further verification. Condition-wise, the metal shows significant surface oxidation and darkening, and there is visible dust accumulated on the base. The overall aesthetic is stylistically consistent with mid-to-late 20th-century artisan craft movement or brutalist industrial art. Hedged language is used in the name because while a signature is present, its authenticity and the exact identity of the artist require physical inspection for confirmation.

Based on my visual analysis of this industrial mixed-media sculpture from the provided image, I have identified it as a mid-century brutalist-style diorama depicting oil field machinery. The work bears a signature consistent with 'Stover Fox' on the live-edge wood base. I am treating this attribution as a working hypothesis, as I cannot verify the signature's authenticity or the artist's identity from a photograph alone. The construction appears to utilize welded or soldered metals—likely brass or copper—on a natural wood plinth. The dark oxidation and dust accumulation are consistent with a vintage item, though I cannot determine the exact age or the structural integrity of the solder joints without a physical inspection. The market for mid-century industrial folk art and 'torch cut' metalwork remains steady, with demand coming primarily from collectors of brutalist decor or petroleum industry memorabilia. The estimate of $150 to $450 is based on the assumption that the signature belongs to a recognized regional artisan and that the piece is a unique hand-crafted object from the late 20th century. If this sculpture were determined to be an unsigned reproduction, a mass-produced piece 'in the style of' Stover Fox, or a later copy, the value would likely decrease to the $40–$75 range. To move beyond this hypothesis and confirm authorship, I would require an in-person examination of the signature's application, documentation regarding provenance, and comparison against verified works by the artist. Professional authentication by a specialist in 20th-century American craft is recommended.
