Set of 8 lithographic bird prints in the style of J.B. Huet and Werner

This item is a collection of eight individual paper sheets, each featuring a hand-colored or color-printed bird illustration. The plates appear to be consistent with 19th-century natural history illustrations, specifically those associated with Jean-Charles Werner. Each page bears visible text markings including 'Ordre 3.', 'Insectivores.', and various species names such as 'Bergeronnette grise' and 'Traquet tarier' in a cursive script. Several plates show a printed attribution reading 'Werner del.' and 'Lith de Langlumé' or 'Lith de A. Belin.', which are consistent with French lithography of the mid-1800s. The birds are depicted perched on branches with fine attention to plumage detail. The paper shows age-appropriate characteristics including irregular deckled or torn edges on the left side, suggestive of having been removed from a bound volume. There are visible signs of foxing, slight discoloration, and minor corner wear. While the markings suggest an 1830s-1850s origin, the exact printing date remains unverified without physical examination of the paper stock and ink. The color application is refined, showing gradients consistent with high-quality period ornithological plates.

I have reviewed the images of these eight ornithological prints, which appear to be mid-19th-century lithographs. The markings 'Werner del.' and 'Lith de Langlumé' are consistent with plates from Jean-Charles Werner’s contributions to French natural history series, such as the works of Temminck or various encyclopedic collections of the 1830s-1850s. Based on what I can see, the paper fibers and the appearance of the foxing suggest a period-correct age; however, I cannot verify the exact printing date or the specific edition from a photo alone. The value range of $400 - $800 assumes these are period-correct hand-colored or high-quality color-printed lithographs from the mid-19th century. This estimate is based on typical market behavior for antique bird prints of this size and stylistic caliber, which remain popular for decorative and historical collections. The visible foxing and irregular edges suggest they were removed from a bound volume, which is common but can affect the value if the staining is excessive. I must emphasize that this appraisal is based on the hypothesis that the markings are accurate to the period. To confirm authenticity, a physical inspection is required to check for plate marks, examine the ink saturation under magnification, and verify the paper's watermark. If these are later mechanical reproductions or 'in the style of' prints from the late 20th century, the value would likely drop significantly to a purely decorative range of $50 - $100 for the set. Market demand for high-quality antiquarian natural history remains stable, but final value is highly dependent on the confirmation of the lithographer and the vibrancy of the color application.
