Mustard pepper salt shaker fish shape

Charming little whimsical and original ceramic object with two fish-shaped containers, probably for salt and pepper but it can also be used to present two sauces on a table. The enamelling is iridescent. It probably dates from the 60s or 70s. It is in good condition, neither crack nor missing, maybe just a slight chip at the eye of one of the fish where to the touch, we feel that it is a little less smooth, but it may be original, and the underside has slight spots. I don't think he had to serve much, if ever. It measures 15 cm in length, 5.5 cm in width, 7 cm in height it weighs about 150 g.
