Both wrong. Kristy and Ann as well.
1. Czechoslovakia was/is in Central and nod Eastern Europe :-)
2. The factory name was "Borocrystal" - so C not K Ann :-) and "Y" not "I" - Kristy :-)
On October 1945, a Decree on nationalisation of large industrial enterprises was declared; subsequently in 1948, a national enterprise Borocrystal associating 55 original smaller plants and decorating workshops, and national enterprise Uměleck√© sklo came into being. In 1953, both two companies together with glassworks Borsk√© skl√°rny were consolidated; thus, a new company named Borsk√© sklo was founded.
To the piece I would also support the oppinion that this piece has been fabricated in Borocryctal, painted probably by O. Gartner.
Simmilar pieces are not rare here, mostly decanters with glasses, painted are horseman, ships, dancers on cracked background.
