Early Waterford Glass piece

"This glass is from a Waterford Glass collection, I think from the 1960s or 1970s. It was left to me after his death in 1991 by my grandfather, Karel (Charles) Bacik, as one of a collection of early Waterford Glass pieces that my grandparents had always used in their home. Karel Bacik had been a glass manufacturer in Czechoslovakia before the war, was imprisoned by the Nazis during the war, then came to Ireland with his young family in 1946 to establish the new Waterford Glass; he subsequently brought over Czech craftworkers, and the enterprise went on to become Waterford's largest employer. As a child I remember eating tinned grapefruit segments from these glasses at dinner, and still love using these beautiful pieces in my own home today."
