“Thank You, Everything” is a picture book by the French illustration duo Icinori — Mayumi Otero and Raphael Urwiller — built around tsukumogami, the Japanese belief that everyday objects gain a spirit after a hundred years of service. The book unfolds as a litany of small thanks (“thank you, blue,” “thank you, morning,” “thank you, glass”) that accumulates, step by step, into a quiet pilgrimage across cities and landscapes.
