Ceramic Item with Japanese 'Art Pottery' and 'Italy' Mark

The image displays the base of a ceramic item, likely a vase, jar, or similar vessel, indicating its origin and manufacturing details. The material appears to be a glazed ceramic or porcelain, characterized by a smooth, off-white, or light cream interior surface. The base is circular with a distinct unglazed rim, revealing the natural clay body, which is a light brown or bisque color, and shows some accumulated dirt and wear consistent with age and use. The central area of the base features an impressed or stamped mark in green glaze, which reads '藝術陶器' (Geishutsu Tōki) meaning 'Art Pottery' or 'Art Ceramics' and below it '伊太利' (Itaria) meaning 'Italy'. This mark suggests the item is either an Italian-made piece sold in a Japanese market, or a piece made in the Japanese market in an 'Italian style' that intended to signify its connection to Italian design or origin. The typography of the kanji characters is clear and well-defined, indicative of a professional application process. There is a small, raised speck or particle in the glaze, possibly a firing imperfection or a piece of foreign matter that adhered during the glazing process, located near the character '器'. The overall condition of the glazed surface appears good, with no obvious cracks or chips visible on the bottom, though the unglazed rim shows typical handling grime and minor abrasions. The quality of craftsmanship appears to be good, with a smooth, even glaze application, although the single speck is a minor flaw. Based on the style of the mark and the linguistic information, this piece likely dates from the early to mid-20th century, possibly post-WWII, when cultural exchange and global trade began to flourish more significantly.
