Nice signed piece of lead crystal, by Dagmar Kudrova. Mainly employed at the Bohemia Podebrady glass-works. Unusual to find a signed piece, as much was produced by glass-cutters to her designs. This may indicate she cut this herself.
This is probably from the 1970's but could be later, as she celebrated 50 years as a glass designer, last year. Very little recorded information about her, other than she worked at Lednicke Rovne 1955-61, and after that, the Household Glass Research Institute, then moved to Podebrady in 1974. Ceska may indicate post 1992 production, though this appears similar to a drinks service designed in 1977, (not Galaxy) and I have nothing here that indicates that she designed at Cesky Kristal.
I will contact someone in CZ, and see what further information they are able to add.
