Daum crystal ashtray signed design modernist 1950-1960

This superb vintage ashtray is made of crystal signed daum. Mouth-blown and molded, this design ashtray was created by the daum crystal factory in the 1950s-1960s. Its free, modern form is timeless. In good condition, it measures 7 cm in height X 13 cm in diameter. I point out traces of use: scratches and chips on the notches. It is signed "daum - france".
