Offered is this beautiful acid-etched and cameo-decorated glass vase, made by Daum of Nancy around 1920. The vase is 5 1/2 inches (14 cm) wide and 5 inches (12,5 cm) tall. It is in excellent condition. It is signed in cameo along with the cross of Lorraine. Under black-light it fluoresces a gentle greenish color, typical of late 19th or early 20th century art glass pieces - so, I would date this piece to be in the late art nouveau or early art deco period.
N.B. A patron pointed out that an American glass-maker (perhaps Fostoria) also made vases of similar shapes and decors. Spurious signatures are always done either in intaglio or are acid-etched - as far as we know, it would be impossible to take a Fostoria glass vase and add a cameo Daum Nancy signature to it.
