Brutalist vase

This brutalist vase of a beautiful size (it measures 31cm in height and 17cm in thickness at its most rounded for a handle width of 18cm) was found in a small village in Haute Provence between fields and mountains, about twenty kilometers from Digne les bains. It is of very beautiful artisanal craftsmanship, probably in terracotta, dark gray/bronze green color. Numbered and signed although the signature is not very legible.
