Naturaly LN was integral part of Czechoslovakian glass industry, all products were exported vias Glassexport. I assume Czech and Slovak glass in Czechoslovakia as the same, we were one state, many Slovak artist worked in Czech part of country and vice versa.
I am still very Czechoslovakian man. I feel Slovakia as part of m country. I
have spent one year in Czecholovakian army together with Slovak friends, we were realy one state. Languages so simmilar like your Wien dialect with language of Germans from Sachsen.
Well it is over. I will be forever Czechoslovakian, not my kids.
Same had happened to our grandfathers. All of them were Austrians without any problem.
