Zelezny Brod Sklo spatter glass vase

This ZBS labeled vase is 7" high x 4.5" in diameter and weighs 2.4 lbs. I have never seen a ZBS vase like this before, however those more knowledgeable of Bohemian glass may not find it unusual. The colors are odd, there is an applied ribbon around the neck and the shape is not typical. What looks like voids in the spatter is, I think, bits of the brown spots from the bottom. I could not resist it, though, as I really like the oddness of it and the colors. The bottom does not look right to me, either, apparently mold blown? It is a very complex piece with at least four layers, not counting the applied ribbon. It is one spatter layer on top of another spatter layer with a clear layer separating them.

I was pretty convinced that this vase was not ZBS, based on how different it is from typical glass that I have seen, but I posted images to glassmessages.com and someone found another labeled vase in similar style on picclick from an old ebay listing. I have included the picclick link at bottom of this post and squeezed a small image of the other vase into my second image. Unfortunately, only one image from that auction survives and the seller, when I contacted them, said they no longer have any of the images but gave me permission to used the remaining image. So now we have two examples of this vase, but there was definitely some artistic license exercised in the execution of the two examples. The ribbon on the second vase, once bright silver, was apparently so infused with silver that it blackened over time.

"The Zelezny Brod glassworks, also known as Železnobrodské Sklo (ZBS), was created in 1948 as a result of nationalization. At this time it was made up of nine glass factories in the town of Zelezny Brod, Czechoslovakia. ZBS is probably best known for it's popular free-formed organic vases and bowls, designed by Miloslav Klinger during the 1950's/60's."

I also find the sticker on the vase a bit confusing. My research says that the Czech Republic was founded in 1993 with the dissolution of Czechoslovakia which seems to conflict with Zelezny Brod (ZBS) which was an entity comprised of nine glass factories in Communist Czechoslovakia. Post 1993, was there a company, or group of companies, which used a label similar to the one on my vase? Did ZBS continue as before? This label was used on glass made post-1993.

I am calling this "Mystery Solved" though I still don't know factory/artist made this vase or who the designer was. I will update this post with any new information and welcome any input.
