AI Appraisal Estimate

This is a hand-colored copperplate engraved strip map, likely from John Ogilby's influential 'Britannia' atlas, the first national road atlas of England and Wales, originally published in 1675. The map features seven vertical columns representing distinct segments of travel routes, specifically those from London to Hith (Hythe) and London to Holy-Head. The layout includes 'ribbon' maps that show the roads with topographical landmarks such as bridges, hills, woods, and local estates depicted in miniature. This specific plate is labeled 'Plate VII' in the upper right corner. The engraving is executed on laid paper and features delicate hand-tinting in green and yellow to highlight forested areas and town boundaries. The text includes mile markers and compass rose pointers for cardinal direction orientation. In terms of condition, the paper shows significant signs of age and historical handling; there is visible foxing throughout the margins, distinct vertical and horizontal creasing from original folding, and a notable v-shaped tear or heavy crease on the bottom right column. The piece is professionally matted with a blue-gray bevelled mat and appears to be housed in a dark wooden frame. The cartography style is typical of the late 17th to early 18th century, showcasing high-quality draftsmanship of the Restoration period.

I have virtually examined this hand-colored copperplate engraving, identified as Plate VII from John Ogilby’s 'Britannia,' first published in 1675. This work is historically significant as part of the first national road atlas. The map exhibits the classic ribbon style, detailing routes from London to Hythe and Holyhead. The typography and geographical styling are consistent with late 17th-century Restoration-period cartography. Regarding condition, the piece shows significant age-related wear, including prominent foxing, historical fold lines, and a visible v-shaped tear in the lower right quadrant. While the hand-coloring is attractive, it is likely a later addition rather than original to the 1675 printing, which is common for these plates. The professional framing and matting add to its decorative appeal but also conceal the paper edges and potential plate marks. The market for Ogilby plates remains stable due to their importance in the history of cartography; however, the heavy foxing and structural damage to the paper significantly limit the premium value typically seen in pristine examples. Comparables for Plate VII in better condition often reach $800+, but the current condition suggests a more conservative valuation. Limitations: This appraisal is based on digital imagery. Full authentication requires an in-person inspection to verify the paper's watermark, ensure the ink is physically recessed into the fibers (indicative of copperplate pressure), and check for any repairs concealed by the matting. I would also recommend a physical examination to confirm if the paper is genuine 17th-century laid paper or a high-quality 19th-century reproduction.
