AI Appraisal Estimate

This is a hand-painted leather lamp shade featuring a four-sided tapered pyramid (mission style) silhouette. The piece is constructed from multiple rawhide or treated leather panels that have been whip-stitched together along the edges using dark leather lacing. The surface is adorned with a vibrant, geometric Southwest or Native American-inspired motif, consisting of bold zig-zags and diamond patterns in a palette of turquoise, violet, crimson red, and black against the natural cream-colored leather background. The top panel clearly displays a handwritten signature that appears to read 'Diane Deyo'. The craftsmanship suggests a custom or artisan-made piece, likely dating from the late 20th century. Condition-wise, the leather shows minor natural texture and slight age-toning, but the paint remains bright and the lacing appears structural and intact without significant fraying. The interior likely contains a wire frame common to these styles. The overall quality reflects a high degree of manual decorative skill and deliberate aesthetic coordination.

I have conducted a visual appraisal of the Diane Deyo signed Southwest-style leather lampshade. The piece exhibits high artisan quality, featuring hand-painted geometric motifs on rawhide panels with robust whip-stitched lacing. The signature 'Diane Deyo' is clearly visible and corresponds with known artisan decorative work from the late 20th-century American Southwest movement. My inspection of the images shows the leather remains supple with minimal age-toning and no significant desiccation, while the pigment saturation in the turquoise and crimson areas remains vibrant. The market for Southwest decor remains stable, particularly for signed, handcrafted lighting accessories which command a premium over mass-produced rustic shades. Comparable sales for similar mission-style hand-painted rawhide shades generally fall within the $200 to $500 range depending on the complexity of the artwork and the artist's reputation. The specific four-sided tapered design and the intact nature of the lacing significantly bolster its marketability. However, limitations exist with remote visual examination. A physical inspection is required to confirm the structural integrity of the internal wire frame (checking for rust or bends) and to verify the leather's pH levels to ensure no chemical rot is present. Authentic rawhide should be translucent when lit; synthetic substitutes can sometimes mimic the look in photos. For a definitive authentication, I recommend provenance documentation or a receipt from the original artisan purchase. Final value assumes the shade is free of hidden punctures and that the paint does not flake upon handling.
