AI Appraisal Estimate

This item is a framed, hand-colored copperplate engraving map titled 'Calabria Citra olim Magna Graecia,' originally produced by the renowned Dutch cartographer Willem Janzsoon Blaeu circa 1640. The map displays the northern region of Calabria, Italy, bordered by the 'Mare Tirreno' (Tyrrhenian Sea) to the west and the 'Mare Jonio' (Ionian Sea) to the east. The piece features classic 17th-century cartographic elements, including a highly decorative title cartouche in the lower-right corner adorned with figures and a coat of arms. Sailing ships are scattered throughout the seas, and the topography is rendered with shaded hills and forests. The print is finished with delicate hand-coloring in pastel blues, greens, and ochres. It is housed in an ornate, dark-toned double frame: the inner frame is a narrow gilded wood profile, while the outer frame is a wider, dark wood with repeating carved motifs. The paper shows characteristic aging with a slight overall yellowing or 'toning' consistent with antiquity. There appear to be faint vertical undulations in the paper, suggesting it is not laid flat against a mounting board, which is often preferred for preserving original antique maps. The craftsmanship of the engraving remains sharp, indicating a high-quality strike from the plate. No significant foxing or water damage is immediately visible through the glazing, though the frame shows minor dust and light surface wear.

I have examined the digital representation of the framed map 'Calabria Citra olim Magna Graecia' by Willem Blaeu, dated circa 1640. Visually, the piece demonstrates the hallmarks of an authentic 17th-century copperplate engraving, specifically the sharp plate marks, characteristic linear engraving style, and the high-quality Dutch paper of the period. The hand-coloring appears contemporary or early, applied with the period-correct restraint in pastel washes. The condition is excellent; the slight paper undulations are a positive sign, indicating the map is not glued to a backing, thus preserving its structural integrity. The ornate double-framing adds significant decorative value, though it prevents an inspection of the verso for the necessary central fold or watermark. The market for Blaeu maps remains robust, as he is considered the pinnacle of the 'Golden Age of Dutch Cartography.' Italian regional maps are particularly sought after by European collectors and interior designers. Comparable auction results for this specific Calabria plate range from $800 to $1,400 for the sheet alone; the professional framing and superior color quality of this specimen push the value toward the higher end of the spectrum. Final authentication is limited by digital viewing. To fully verify this item, a physical inspection is required to confirm the paper's chain lines and watermark (typically a crossed arrows or shield for Blaeu) and to ensure the coloring is not modern offset lithography. I would also recommend removing the dust cover on the back to check for the presence of Latin or French text on the verso, which would confirm which edition of the 'Theatrum Orbis Terrarum' this map originated from. Provenance documentation regarding its acquisition would further solidify this valuation.
