AI Appraisal Estimate

This set consists of two sculptural art glass decorative items in a rich olive or avocado green transparent hue, typical of mid-century aesthetics. The primary piece is a swan-form bowl featuring an elegant, elongated neck that curves upward and tapers into a stylized head, with a deep, lobed vessel body designed to hold small objects. The secondary companion piece is a snail or nautilus-inspired bowl, characterized by a tight, decorative spiral scroll at the front end and similar undulating, scalloped edges that form a cradle-like vessel. Both pieces are manufactured from heavy, hand-pressed, or hand-blown glass, showcasing the fluid, organic lines popularized by companies like Viking Glass or L.E. Smith during the 1960s and 1970s. The glass contains minimal inclusions, though subtle air bubbles may be present upon close inspection, which is common for art glass of this era. The surface appears to have a high-gloss finish with no significant clouding or 'sick glass' syndrome visible. There are no obvious chips or cracks in the curving extremities, which are vulnerable points. The bases are likely ground flat to ensure stability. These items represent high-quality domestic glass production from the American mid-century period, and their excellent clarity suggests they have been well-maintained without significant abrasive wear.

Upon visual examination of this Mid-Century Modern art glass set, I have identified the pieces as characteristic of Viking Glass Company’s production, specifically in their popular 'Avocado' or 'Olive Green' colorway. The set includes the iconic swan dish and the matching snail/scroll bowl. The glass exhibits the correct clarity, weight, and light refraction expected from hand-pressed American glass of the 1960s-1970s. The organic, fluid lines and the thick, sturdy construction are hallmarks of the Viking aesthetic. The market for mid-century colored glass remains robust, particularly for 'animalia' forms which have high crossover appeal among both art glass collectors and interior designers. Individually, these pieces often retail for $50 to $85. As a matched set in excellent condition with no visible chips to the delicate neck of the swan or the scroll of the snail, they carry a premium. The absence of 'sick glass' (internal mineralization) significantly preserves the value. Critically, this appraisal is based solely on high-resolution digital imagery. Without a physical inspection, I cannot verify the presence of 'flea bites' on the base or microscopic surface scratches that might detract from a 'mint' rating. A full authentication would require checking for the original silver and crimson 'Viking' foil labels, as these pieces were rarely signed with an etch. In-person examination would also confirm the absence of modern mass-produced reproductions, which often lack the precision and depth of color found in original New Martinsville/Viking production. For insurance purposes, I recommend documenting any UV fluorescence, which can help verify the specific chemical composition of the glass batch.
