Kanti pitchers are from the Languedoc region of south west France. They are similar to water cruches except that they are entirely closed on top - there is no lid to open and close (or lose!). They were originally used for fetching water from the village fountain. Early twentieth-century.
See similar example in Poteries d’Eaux, page 48.
