Trio salt shakers pepper vegetables and fruits in slip

Charming set of three ceramic salt shakers or pepper trees in the shape of fruits and vegetables, an eggplant, a tomato and a lemon, we can imagine putting salt, pepper and turmeric for example. They probably date from the 60s or 70s. They are in good condition, neither crack nor missing, the plastic caps are functional, just a few marks of use underneath. They measure between 5 and 7cm in height and the whole weighs about 150 g.
