Lars Hellsten for Skruf Glasbruk

Lars Hellsten for Skruf Glasbruk
Green decanter with Medallion.
6" tall
4"wide
Signed Hallsten Skruf HlF or HLF? 1-1
From reading some info on Scandinavian Glass Collectors FB page... I learned he was there from 1964-1972.
Didn't realize this was a signed piece until after cleaning which took a while...it was so dirty.
Found in one of my secret places I like to pop into every now and then to see what treasures they my have.
What is the symbol of the medallion? Viking face was stated online but I'm not positive on that.
Easier to identify when signed and thanks to FB group Scandinavian Glass Collectors site I went through that helped with this piece.

Thanks everyone and Happy Hunting
