Cobalt blue glass goblet

This is a freestanding cobalt blue glass goblet, held in a hand for scale against a retail-style background featuring clothing racks and a shopping cart. The physical characteristics include a deep, vibrant cobalt blue color throughout the translucent glass material, a wide flared bowl featuring vertical paneling or optic fluting, a multi-tiered or ribbed knop stem, and a round, flat foot base. There is a small price or retail sticker visible on the base. The item displays generally good surface gloss with no glaring chips or cracks immediately discernible from this angle, though the piece remains unauthenticated and of unknown exact age or manufacturer. There are no visible maker's marks or signatures apparent in the photograph. Stylistically, the piece shares similarities with mid-century or vintage pressed and blown glassware, but without physical inspection, stamps, or etchings, its exact origin cannot be determined. The owner provided additional unverified context stating "Gotham itched in base", referencing a potential etching on the bottom, though this cannot be verified from the provided image alone. The overall craftsmanship suggests mass-market or decorative glassware production, displaying standard mold seams typical of pressed glass items.

Based on the visual evidence provided, I can observe a freestanding cobalt blue glass goblet featuring a wide flared bowl with optic fluting, a multi-tiered ribbed knop stem, and a round flat foot base with a retail sticker. Per user submission: the owner notes an etching on the base reading 'Gotham'. Based on what I can see, I cannot verify the exact age, manufacturer, or the purported base inscription from a photograph alone; physical inspection would be needed to confirm these details. The estimate range of $45 to $75 assumes the item corresponds to mid-century or vintage decorative glassware of this type. General market demand for vibrant cobalt blue glassware of this era remains steady among decorative collectors. However, if physical inspection reveals the piece is a later reproduction, replica, or lacks any connection to the 'Gotham' reference, the market value would likely adjust downward to the $15 to $30 range typical of unmarked mass-market glassware. To fully evaluate authenticity and potential attribution, one would need an in-person examination, hallmark or signature verification by a specialist, and professional provenance research.
