The finely drawn brushwork here and the distinctive bright blue are characteristics of pieces made at Seto in Japan in the 19th and early 20th centuries. The city of Seto is located in the Aichi Prefecture and was the location of one of the Six Ancient Kilns of Japan. Pottery was produced there from the 13th century onwards. The kilns took part in the export of decorative wares to the West from the second half of the nineteenth century onwards producing a wide variety of forms, in particular pairs of vases, but with a speciality in flat plaques and table tops, for which they gained something of a monopoly. Their pieces are usually marked, to include the characters for Seto, and this pair of vases may have originally been signed themselves but with the marks partially obliterated in the firing process. The quality here matches anything else produced by the factories but the light weight and thinly potted body suggests a dating to the early 20th century rather than before, probably during the Taisho period (1912-1926). Nevertheless the skill in craftsmanship is obvious and contributes to a highly attractive pair of ornaments for a contemporary interior.
