This is a vintage French porcelain Pierrot mustard pot, or moutardier. It is a collectible object, likely dating from the 1920s or 1930s. The figure is a stylized representation of Pierrot, a classic pantomime character. It typically comes as part of a condiment trio, including a lid (the orange cap) and a small spoon. The pot held mustard and was used as a whimsical table collectible during the Belle Époque era.
