Age Estimate
Circa 1950s. The vibrant lime green color and concentric oval geometry are highly characteristic of mid-century David-Andersen production.
Cultural Significance
Represents the pinnacle of the 'Scandinavian Look' that dominated mid-century interior and fashion design, emphasizing nature-inspired colors and superb industrial-craft hybrid techniques.
Condition Notes
Excellent condition. Surface shows no visible chips ('flakes') or hair-line cracks in the enamel. Gilding appears intact on the edges. Pin assembly is straight.
Value Estimate
$150 - $250 USD. Value depends on the rarity of the color (lime is desirable) and the lack of damage to the enamel surface.
Care & Maintenance
Avoid ultrasonic cleaners or steam. Clean only with a soft damp cloth and mild soap. Prevent dropping, as vitreous enamel is glass and will shatter or chip upon impact.
