A conceptual publication by On Kawara, *Thanatophanies* exemplifies the artist's profound engagement with time, existence, and mortality through his signature systematic methodology. Numbered 17/180 in pencil on the colophon, each sheet is chronologically stamp-numbered on the reverse with dimensions, reflecting Kawara's meticulous, almost ritualistic approach to documentation. Published by Edition Parco Co., Ltd., this excellent-condition work is housed in its original fabric-covered box bearing the artist's name in Japanese, preserving the object's integrity as both an artwork and a carefully considered artifact.
