Tea bowl with pine needle design, red Raku ware

This tea bowl is made of red clay and coated with sand glaze. The acute white lines of the pine needle give a sharp impression.
It has a seal of ‘楽 (Raku)’ inside the foot ring and a note of ‘楽 三代ノンカウ作 (By Nonkau, 3rd Raku)’ on the box for the tea bowl. Nonkau is another name of Donyu (1599-1656), an expert potter of the Raku family.
