Vintage 6" Round Thick Walled Engraved sides retailer crystal Ashtray signed by artist

Vintage 6" Round Thick Walled Engraved sides crystal Ashtray signed by artist. This is a unique Ashtray, it has 3/4" thick wall sides, it is engraved and etched on the exterior side walls with a floral and leaf pattern. It has three cigar size resting troughs. The artist did sign the bottom although I cannot make out the first name, the last name appears to be "Mehr". This is a retailer substantial piece, it is heavy and is in good used condition with just a couple small scratches on the bottom. Possibly Czech. This would make a beautiful shelf or tabletop decor. It is just lovely with the engraving.
Measures 6" outside diameter, 4 3/8" inside diameter Ash bowl, 2 3/8" tall outside, just under 2" tall inside ash bowl.
