Thunderbird/Eagle Signed Relief Art

Large-scale vintage mixed-media relief artwork depicting a highly stylized bird figure, likely intended as a Thunderbird or eagle, rendered with formline-inspired shapes associated with Indigenous art of the Pacific Northwest Coast. The deeply textured, raised composition is executed in earthy shades of ochre, tan, brown, rust, and black against a circular ground and mounted within a simple square frame. Signed by the artist at the lower right; the signature appears to read “P. Miller” or similar, but the artist has not been definitively identified. The reverse incorporates reused U.S. Gypsum insulating sheathing marked “USG,” “Insulating Sheathing,” and “BIMA,” suggesting a studio-made construction rather than a commercially manufactured decorative panel. Due to the unidentified artist and lack of provenance, the work should be described as Northwest Coast–inspired rather than attributed to a specific Indigenous nation or artist.
