AI Appraisal Estimate

This is a vintage footed highball or champagne glass featuring a distinct Mid-Century Modern aesthetic. The piece is constructed with a clear glass cylindrical bowl that transitions into a uniquely designed base. The stem and square foot are crafted from a 'smoked' or olive-tinted dark glass, providing a sharp color contrast typical of mid-20th-century glassware design. Physically, the glass stands approximately 6 to 7 inches tall. The bowl is perfectly vertical with a flat base, while the stem is relatively short and tapered, leading down to a square-shaped foot with rounded corners. The craftsmanship suggests machine-blown production with a hand-finished quality, as evidenced by the clarity of the glass and the clean lines of the square base. No obvious maker's marks are visible in the photograph, but the style is reminiscent of manufacturers like Libbey or various Scandinavian glassworks from the 1960s or 1970s. Regarding condition, the glass appears to be in excellent used condition with high clarity; there are no immediate signs of chips, cracks, or heavy clouding from dishwasher use. The surface maintains a reflective luster, and the connection point between the smoked stem and clear bowl appears secure and well-integrated. This set would be considered a fine example of period barware, emphasizing geometric shapes and contrasting tones.

I have virtually examined this Mid-Century Modern footed highball glass. The piece displays the characteristic 'smoke' or 'amber-smoke' tinting and geometric square-foot base popularized in the 1960s and 70s. The condition appears to be 'Excellent Vintage Condition,' showing high clarity without the 'sick glass' clouding often caused by abrasive dishwasher detergents. The fusion point between the bowl and the smoked stem remains crisp, indicating high-quality machine-blown manufacturing. While the design is reminiscent of Scandinavian makers like Iittala or Kastrup-Holmegaard, the square foot and stem transition are most closely aligned with the 'Classic' or 'Mid-Century Modern' lines produced by the Libbey Glass Company (USA). Market demand for individual replacement pieces or 'replacements.com' style inventory remains steady, though value is significantly higher when sold as a complete set of 6 or 8. Currently, the market for MCM barware is saturated, making individual unsigned glasses accessible and moderately priced. Factors impacting value include the absence of a maker’s mark and the relative commonality of this specific silhouette. For full authentication, I would require an in-person inspection to check for acid-etched signatures on the base, analyze the weight/lead content, and feel for mold seams which would distinguish mass-production from artisan hand-finishing. Provenance or original 'Libbey' foil stickers would increase the certainty of this valuation. Without physical testing of the glass density or documentation, this remains an attribution based on visual stylistic markers.
