ADDITIONAL NOTES FOR THESE DESIGNS
The Tsuchiya family collection includes several copies of artist proofs of two woodblock print designs featuring single rats. These were stored in a folder with uncirculated copies of souvenir prints, and the family reported that Rakusan had intended to prepare these two designs for similar use. Rakusan probably created these designs circa 1947, presumably in anticipation of the Year of the Rat which would have begun in early 1948. It is uncertain if final versions of either design were ever actually published and circulated. The uncirculated artist proofs have no signatures or seals.
sp. (unclear which species is intended). These two designs are the only representations of rats or mice among Rakusan's artworks.
