A Daum Nancy glass dragon vase

A Daum Nancy acid etched and internally decorated glass dragon vase
early 20th century
Incised DAUM NANCY FRANCE with the Croix de Lorraine.
height 12 1/8in (31cm)
Provenance: Property from the Estate of Ruth Harvey, Bel Air, California.
Condition Report: Scattered areas of sticker residue. A few small fleabites to rim. Dirt to interior from use. Some typical wear to the decoration and a few light abrasions. Scattered trapped air bubble inclusions. Normal wear to the footrim with a few fleabites. Some heavier wear around the circumference of the neck leaving the area with less of a glossy finish. When held up to the light with light behind the vase, there is a line visible (around center of vase) to the interior which appears to be a manufacture flaw rather than a hairline which is mostly hidden by the decoration.
