French Renaissance grotesque head spilling a bunch of fruits

16th century French Renaissance high relief sculpture in tuffeau stone, representing a grotesque head spilling a bunch a fruits and flowers. The face features are finely rendered, like the eyelids or the lips, the mouth letting fall a bunch of fruits and flowers, like several acorns...
According to this variety of limestone, the piece was possibly made in the French Loire region.
It bears an old provenance label on the back, mentioning the Abbey of Bourgueil.

Dimensions: 21 cm high (26 cm support included)

Good condition: old breaks around the piece and some scratches, but no restorations. Nice outside patina.
