Koji Koizumi Postcard Collection "Schrödinger's Tower"

Set of 12 postcards, in a case.
 The cover illustration is inspired by the quantum mechanics thought experiment "Schrödinger's Cat."
 The state in which existence and non-existence, being and not existing, overlap simultaneously is expressed in the symbolic form of a "tower." This is a collection of postcards by Takashi Koizumi depicting a mysterious world where reality and fiction intersect.
