AI Appraisal Estimate

This is a detailed, monochromatic steel-plate engraved map of the French department of Aude, originally published by Victor Levasseur in his renowned 'Atlas National Illustré des 86 Départements et des Possessions de la France' circa 1850. The map itself is centered and surrounded by an elaborately decorative vignettes typical of the mid-19th century French style. These vignettes include portrait medallions of notable figures in the upper corners, a topographical scene at the bottom featuring agricultural barrels and local industry, and detailed statistical panels on either side containing data on population, area, and administrative divisions. The engraving displays fine detail in the cartography, showing roads, rivers, and towns. The paper is an off-white or cream-toned heavy wove paper reflecting its age. There are visible signs of aging including slight undulation of the paper and minor foxing or light staining along the margins. The craftsmanship is high-quality, characterized by delicate cross-hatching and masterful use of light and shadow in the decorative border illustrations. The bottom center is boldly titled 'DÉPT DE L'AUDE'.

I have examined the digital representation of this Victor Levasseur map of the Département de l’Aude (circa 1850). The piece exhibits the hallmark characteristics of a genuine steel-plate engraving from the 'Atlas National Illustré,' specifically the high-contrast decorative vignettes and dense statistical side-panels. The monochromatic state suggests it is likely an uncolored leaf from a standard edition of the atlas. Visually, the paper shows minor undulation and light marginal foxing, which is consistent with mid-19th-century heavy wove paper; these defects are typical and do not significantly detract from the aesthetic value, though professional deacidification would be beneficial. The market for Levasseur maps remains stable due to their high decorative appeal. While many department maps were mass-produced, Aude is a popular region for collectors of French cartography. Comparable sales for uncolored or lightly toned Levasseur plates typically fall within the $150 to $250 range, whereas hand-colored versions in pristine condition can command upwards of $350. Limitations to this appraisal include the inability to verify paper texture, watermark presence, or the depth of the plate mark via digital image. A definitive authentication would require a physical inspection to check for modern reproduction signatures (such as halftone dots) and to confirm the absence of acidic adhesive residue on the verso. For a full valuation, provenance documentation or a contemporary binding fragment would be ideal. The current valuation assumes the item is an original 19th-century strike and not a later lithographic facsimile.
