Mid Cent Mod Strömbergshyttan Vase Signed heavy etched with minstrel and Woman

Mid Century Modern Stunning Vase, very heavy glass. 1950s? Approx 10.5 tall by 5 inch wide. Etched with minstrel on one side, woman in window on other side. I may be wrong on the Strommbergsshyttan...Please let me know if you know anything about this vase. I would love to know more about it! From an estate that I am sorting through. The owner had incredible taste. Please see my other listings as I have many Depression Era glass, including clear and amber glass, as well as unique Mid Century items and cobalt blue pieces.
