AI Appraisal Estimate

This is a framed, limited edition lithographic print titled 'Powderman' by the artist Bill Granstaff, copyrighted in 1977. The artwork features a technical still-life of vintage blasting equipment, including a wooden DuPont blasting machine (plunger-style detonator), Atlas dynamite sticks, rolls of Clover Brand safety fuse, and various blasting caps and tools. The color palette is composed of realistic earth tones, muted reds, and blues on an off-white background. The piece is hand-signed by the artist in the lower center-left and numbered 804/1000. It is housed in a decorative, ornate gold-gilded frame featuring a repeating leaf and scroll pattern. The print appears to be in good condition with no visible foxing or water damage, though it is slightly recessed behind protective glass. Notable text includes 'COMMISSIONED BY BENNIE MOUSER, WEST KY. EXPLOSIVES, INC.' at the bottom right, indicating a specific regional or industrial provenance. The style is 20th-century realism, specifically intended for the collectibles market within mining or industrial history circles.

I have virtually examined this framed, limited edition lithograph titled 'Powderman' by Bill Granstaff (1977). The work is a fine example of 20th-century technical realism, specifically catering to the niche mining and industrial history sector. The print displays a hand-signature and is numbered 804/1000, suggesting a fairly large edition size which limits individual rarity but maintains consistent market presence. The condition appears 'Good' to 'Very Good,' with no visible foxing, fading, or moisture ingress. The ornate gilded frame is an asset, though it likely accounts for a significant portion of the total valuation over the print itself. The market for Granstaff’s regional and industrial prints is stable but niche. Values are driven primarily by 'Man-Cave' appeal and historical interest in the DuPont and Atlas brands. Comparables for signed Granstaff lithographs typically fetch between $75 and $125 unframed, while the inclusion of the customized framing and the 'West Ky. Explosives' provenance adds specific regional value to collectors in Kentucky or the blasting industry. Critically, this appraisal is based on photographic evidence. I cannot definitively verify the authenticity of the signature or the state of the paper beneath the matting without a physical inspection. A professional inspection would check for 'acid burn' from non-archival backing and verify the ink type. To reach the higher end of the valuation, provenance documentation linking the original commission by Bennie Mouser to the current owner would be beneficial. Scientific testing (such as UV light examination) would be required to confirm the absence of prior restoration.
