Hello - I believe Josephinenhutte was really made in Poland - I apologize if this is the wrong category.
I have several beautiful pieces from the Josephinenhutte/Josair series "Josephine" which I have today learned was designed by Sigfried Haertel around 1905. The examples that I was able to find online today (all very antique) do not seem to have a maker's mark on them - and the parties selling the items reference the work of Stefania Zelasko at The Karkonosze Museum to support that their Josephine items are authentic.
My glasses have the "JH" inside a shield below a crown sandblasted mark - and I am wondering if anyone knows when Josephinenhutte adopted the mark? I am trying to date my set as close as I can - and have come across some confusion as some online sources say Josephine was discontinued in 1958 while others say 1981.
Any and all help appreciated!
Thanks so much -
