Creation Period
Late 20th Century to Contemporary (likely a reproduction in the Arts and Crafts style)
Dimensions & Format
Estimated 8-10 inches in height; pentagonal tapered lantern format.

Condition & Value Assessment
Condition Assessment
Fair to Good; shows significant surface wear, minor delamination of mica layers, and scuffing.
Estimated Market Value
$50 - $150 USD
Auction Estimate
$40 - $100 USD
Provenance History
Unknown; likely a residential fixture or estate find. No visible maker's marks or foundry stamps are present in the provided image.
Art Historical Significance
Represents the enduring legacy of the American Arts and Crafts movement's 'honest' use of natural materials. While likely a modern reproduction, it follows the design philosophy of emphasizing organic textures and warm, diffused light typical of the early 1900s.
Notable Features
The irregular, mottled 'butterfly' texture within the mica sheets and the dark industrial finish of the metal channeling.
Condition Issues
Visible surface scratches, spotting (possibly moisture damage or resin degradation), and dust accumulation. The metal frame shows some edge wear and oxidation.
Conservation Recommendations
Gently clean with a dry microfiber cloth; avoid liquids as mica is porous and water can cause delamination. Keep away from high-heat bulbs to prevent further scorching of the bonding resins.
