To further confirm the date period suggested above, the country identification on the label is Czechoslovakia which would put the latest date to 1992 and earliest 1945. However, given the style - especially the shade of blue and gold enamel - the date 1960s/70s seems most reasonable. Although I can't see the sticker, its format appears very suggestive of that era.
As an aside, I do not think that these are wine goblets given the long stem and constrained bowl. however, I would not be dogmatic on that point.
