Tall 10.25” Robert Held Art Glass Vase

I’d like to say this is just my educated guess on the maker. Sometimes their pieces only had the foil label on the base and it comes off. I’ve handled many of his pieces over the years and I strongly suspect this is from his studio. The waves are very well done , they are meaty textured and is an over alll nicely made piece. 10.25” tall 4” diameter
