Design bottle in enamelled sandstone in the taste of Suzanne ramie

A magnificent sandstone with a fine and subtle design. To be compared to the work of suzanne ramie who worked with picasso in madoura. The signature also goes in this direction but I remain very cautious indeed I have not found this style of signature being officially attributed to him. In any case the curves are superb finesse and roundness, a nice work on the email. I leave you to judge. It measures 23 cm, about 10.5cm in diameter and 2.5cm at the opening of the neck.
