Zoological print consistent with early 19th-century naturalist illustrations

This item is a color print of a large cat, identified by the script at the bottom as 'Der Panther' and 'Felis Pardus'. The illustration depicts the animal in profile, featuring detailed tawny-orange fur with black rosettes and a pale underbelly, consistent with stylized zoological engravings or lithographs from the late 18th to mid-19th century. The print is professionally matted in black with a gold inner border. The frame is a notable feature, displaying a burl wood or tortoiseshell-style reddish-brown finish with intricate geometric parquetry inlay, including repeating diamond patterns. While the user suggests a connection to 'Robert-Grace,' a label visible on an adjacent item in the photo reads 'Robert-Grace, Hollister, CA,' which may indicate a framing studio or gallery rather than the artist of the print itself; this attribution remains unverified without physical inspection. The print appears to be in good condition behind glass with no visible foxing, while the frame shows sharp corners and a high-polish finish. The specific printing method (e.g., hand-colored engraving versus modern offset lithography) cannot be determined from the image, so the age is assumed based on the historical style of the typeface and subject matter.

Based on my examination of the image provided, this item appears to be a zoological illustration of a leopard, titled 'Der Panther' (Felis Pardus), consistent with Continental European naturalist engravings from the early-to-mid 19th century. Per user submission, there is an attribution to 'Robert-Grace' via a gallery label. However, I cannot verify from a photo whether the print is a period hand-colored engraving or a modern high-quality offset lithographic reproduction. The value estimate primarily reflects the high decorative appeal of the frame, which features intricate parquetry inlay and a burl-style finish, often associated with specialty framing studios like the one identified in Hollister, CA. Market demand for 19th-century natural history prints remains stable among collectors of 'Cabinet of Curiosities' decor. If this is a period engraving (circa 1830-1850), the value sits in the upper range provided. If it is a modern reproduction housed in a high-quality frame, the value would likely decrease to $150–$250, as the market would then treat it strictly as a decorative accessory rather than an antique. I cannot confirm the printing technique, paper age, or the exact maker of the parquetry frame without a physical inspection. To verify authenticity and refine this estimate, an in-person examination by a paper conservator would be required to check for plate marks, watermarks, and ink absorption patterns. The 'Robert-Grace' label likely refers to the framing provenance rather than the artist, which also warrants further documentation of the studio's history. Condition appears excellent behind glass, though I cannot observe potential hidden mounting damage or UV-related fading through the digital image alone.
