For our “Artist Series” puzzle pairs, we commissioned illustrations from the Japanese artist Asahi Nagata. In the unique, sophisticated style of risography, Asahi renders simple objects beautifully. We offer this special addition to our early stem stable, to help learn numbers 1–20.

Asahi Nagata was born in Sapporo, on the island Hokkaido in Japan. She now lives in Minneapolis, Minnesota with her baby and two cats, Journie and Shi-Shi. Asahi works at a tiny workstation in the corner of her living room during her baby's nap time or after she goes to bed. Her work is inspired by vintage risographs, screen printing and linocuts. To unwind, Asahi may be founding going for a walk in her local park, reading manga, or visiting local vintage shops.
