This 1975 woodblock print, catalog number 413, was created in close sequence with Work 406, the seven-number gap suggesting both works emerged from the same period of sustained studio activity. The proximity of the two "Work" entries in Funasaka's sequence invites comparison, with the compositional differences between numbers 406 and 413 revealing the incremental variations through which the artist advanced his formal investigations. Funasaka's working method, producing geometric abstractions in a continuous numbered series, resembles the systematic approach of a researcher testing variations rather than the episodic inspiration model associated with romantic notions of artistic creation. Each work builds on the findings of its predecessors while introducing new formal propositions. The print represents one data point in an artistic experiment spanning decades, gaining significance both as an individual composition and as part of the larger sequential structure.
