Mid-century modern style ribbed glass tumblers

A collection of tall beverage glasses or tumblers, featuring at least four smoke-colored (brown/grey tint) glasses and one clear glass in a matching pattern. These tumblers exhibit a cylindrical form that tapers slightly toward a rounded, pedestal-like base. The lower half of each glass features vertical optic ribbing or fluting, a design element that adds texture and reflects light, while the upper portion remains smooth. Based on the silhouettes and the use of 'smoke' glass, these items are stylistically consistent with pressed glassware manufactured during the mid-20th century (approximately 1960s-1970s). The design is reminiscent of patterns produced by companies such as Libbey or Anchor Hocking, though no specific maker's marks or logos are visible in the image to confirm a manufacturer. The glasses appear to be in good used condition, with some surface dust and retail price stickers visible on the side and base, which is expected for items in a thrift or secondary market environment. The quality of the pressed glass suggests mass-market production intended for everyday dining. Without physical inspection for mold seams, weight, or etched signatures, a specific brand attribution remains a hypothesis based on visual styling.

Based on my visual analysis of the provided image, I am examining a five-piece set of mid-century style glassware featuring characteristic optic ribbing and a weighted pedestal base. The set consists of four smoke-tinted tumblers and one clear glass, all sharing a consistent silhouette. From this photograph, I can observe the general form and condition, which appears consistent with mass-produced tableware from the 1960s or 1970s; however, I cannot verify the specific manufacturer, such as Libbey or Anchor Hocking, without holding the items to inspect mold seams, weight, and potential base markings. The presence of retail price stickers suggests these are currently in the secondary market. The estimated value of $25 - $45 is predicated on the hypothesis that these are vintage mid-century pieces in good condition. This range reflects general market demand for 'atomic era' or 'retro' kitchenware of this type. Because these pieces lack a confirmed designer attribution, their value is driven primarily by their aesthetic appeal and utility rather than brand prestige. While I can see surface dust and stickers, I cannot definitively rule out minor chips or glass sickness (clouding) which would require a physical inspection to detect. To confirm the origin, one would need to compare the base dimensions and rib patterns against known catalog specifications from major mid-20th-century glassworks. If these were determined to be modern reproductions 'in the style of' rather than vintage originals, or if significant structural flaws were found upon inspection, the market value would likely decrease to approximately $10 - $15 for the set.
