Offset printing. The paper is 220-kg matte coat. Although it probably doesn’t make sense in other countries, the Japanese pronunciation of two as ‘ni’ is reminiscent of the Japanese for a cat’s meow, which is ‘nya’. So I combined the cat-voice two and Kuro and Hachitaro as a yin-yang on the zero. Of course the background is a tiger pattern.
The drypoint etching work used on the back side is Tengu, derived from my 2020 Prophetic Beasts series. The stamp part is a tiger footprint.
