Vintage cut crystal whiskey decanter

A cut crystal decanter for whiskey, cognac, or other spirits from the 1950s/60s. Made in france, beautifully crafted (lead content over 24%) and heavy (almost 1.7 kg), it's hard to believe it was produced for esso, whose name appears under the base of the decanter. It's in perfect condition, very transparent, with no missing parts or cracks. Above all, it has its rubberized washer on the stopper, which ensures the decanter's watertightness, which is not always the case.
