AI Appraisal Estimate

This item is an iridescent art glass vase featuring a tapered form with a flared rim and a slightly bulbous shoulder, narrowing down to a weighted base. The glass displays a vivid blue and purple iridescence with a feathered or 'pulled feather' pattern consisting of fine, horizontal wavy lines and darker blue vertical striations. The surface appears to have an oiled or metallic sheen characteristic of luster glass. The owner notes that the piece is signed 'Lundberg' and dated either '04' or '09'; however, this signature is not clearly legible in the provided photograph and remains unverified without physical inspection. The design is stylistically consistent with late 20th to early 21st-century studio glass, specifically pieces produced in the manner of Lundberg Studios or similar American art glass houses inspired by Art Nouveau Favrile glass. No significant chips or cracks are immediately visible, though minor surface wear consistent with display might be present. In-person verification is required to confirm movement, age, and maker attribution.

Based on the image provided, I have examined this art glass vase which exhibits a pulled feather design and iridescent luster synonymous with contemporary American studio glass. The owner indicates the piece bears a signature for 'Lundberg' dated '04' or '09'. While the form and surface treatment appear consistent with works produced by Lundberg Studios, I cannot verify the signature's presence or legitimacy from the photograph provided. The value of $250 - $450 assumes the attribution to Lundberg Studios is accurate and that the piece is in excellent condition. This estimate reflects the general market demand for signed studio glass with complex iridescence. From the photo, I can observe the metallic sheen and horizontal wavy lines, but I cannot determine the presence of internal flaws, shelf wear, or potential repairs without a physical inspection. The market for studio glass is highly dependent on maker attribution; if this piece is found to be unsigned, an unattributed contemporary copy, or produced by a lesser-known house in the same style, the value would likely decrease to the $75 - $125 range. To confirm this attribution, a physical examination of the signature under magnification and lighting is required, along with a review of the pontil mark and glass weight. The current estimate is a hypothesis based on user-supplied information and visible stylistic cues, not a statement of authorship.
