Polish Vintage Art Glass tear drop paperweight

Beautiful Marian Pyrcak hand-blown art glass paperweight. Great condition, no chips or cracks. There is a small inclusion in the colored part of the glass that can be seen in the 4th picture. The "M" in Marian's signature is also inverted, possibly because this was a second due to a couple of air bubbles and the inclusion? I'm only speculating on that part.
