Demijohn green about 15 l, very old

Demijohn green about 15 l, with very pretty bubbles in the glass, and the neck, very old "slashed" as the only way that their blowers knew at the time to cut the glass. Edge of the neck but not smooth polished by time, which gives it a very charming guarantee of seniority (see photos). The glass is also marked with a few small bubbles. Quite rare. H 43 X D 36 cm.
