Very chic with its sleek shape with cut sides, its narrow base and its Art Deco design, the cap and the neck are marked 49.
The shoulder is wider than the base, which gives a nice rounding towards the inside of the body, reminiscent of the female waist.
There is no sign of Saint Louis brand, which is explained by a manufacture prior to 1936, when a simple label was affixed.
Dimensions: total height 21 cm with the cap, base width: 8 cm, outer neck width of 4.5 cm and interior of 2.5 cm
