Vintage “rope” slip ceramic planter

The planter is in perfect condition, no accidents, no cracks or chips. It is a very beautifully crafted ceramic, heavy and opulent, whose enamel has remained very fresh, shiny and without stains. The entire slip exterior evokes a coiled rope, dark straw yellow, and is very embossed. The enamel inside the pot holder is smooth and white. The piece is numbered on the reverse under enamel. The first number indicates the model, and the second the height of the piece, 17 cm. The opening diameter inside the collar at the top also measures 17 cm. The pot holder has probably been used very little. We can see some small black dots deep inside, which are not stains, but which are part of the enamel. Quality French work from the first half of the 20th century.
