This is an unusual vintage Desk item....a signed Daum Crystal Triangular shaped Bowl, with an attached swivel mount and dip Pen, from the 1940-1950 Period. The signature is in very small script "Daum France" (see Photo).
Although some might call this an "Ashtray" base, I really think the concave dip at the front of the bowl is meant to hold the Pen when it is wet with ink and the writer has not ceased writing, but is pondering what next to scribe!! (see Photo illustrating this). The glass is in excellent condition.
It is the original Pen with a single "gold" band and matches the receiving holder, which is on a swivel ball joint in gilded brass, and swivels very well! There is no name on the Pen, but it has an 18ct Nib which is signed "Gold Starry". It doesn't appear to have been ever used...
A wonderful Daum item that will look great on any style desk !!
