Extremely rare chalice-shaped vase in colorless, opal, and brown-lined glass. The autumnal decoration is acid-etched in cameo within vitrified layers of pink, yellow, and green powders, partially polished and enhanced by multicolored cabochon appliqués treated with gold (acorns, cockchafer), on a slightly granular background. Magnificent luminous effect! Ref: Daum Master Glassmakers by Noel Daum, Editions Denoël
