Cabbage sauceboat in barbotine Portugal

Adorable and original slip sauceboat perfectly imitating a cabbage leaf with its beautiful green color, its raised veins and the stem acting as a handle. This shape, which resembles a swiss cabbage leaf, must be quite rare, because I had never seen one before. Underneath is a stamp indicating that it comes from a factory in portugal and a number written by hand, a factory that I have not yet managed to identify. This sauceboat probably dates from the 60s or 70s. It is in very good condition, no cracks or chips, just a microscopic chip on the spout where the thickness of the enamel is a little less. It measures 17.5 cm in length, 10.5 cm in width, 7.5 cm in height at the handle and about 5 cm in height at the cabbage leaf.
