Toki-no-Wasuremono Gallery - similar print by Ishii Tsuruzō from 1921 Unsigned and undated. There is the artist's seal in red in the lower right corner. Also, there appears to be seals in the right border which have been abraded and are therefore unreadable.
The relationship between the Lyon Collection copy and the one shown by the Seattle Art League is interesting. The Lyon Collection print might be a proof printed before the final edition. Strengthening this argument is the fact the by comparing the one in the Lyon Collection and that of the Seattle group was printed with, at least, one less block than the Seattle sheet.
