The signatures given here are Hiroshige's actual signatures copied from the books with the dates of publication put on view in the exhibition. The compiler wished to give more of these signatures according to the chronological sequence but he could not do so as most of the illustrations have no signatures.

Of the above signatures, those from 1 to 8 are dated 1818 and have been taken from No. 238. 9 1840, from No. 246. 10 and 11 1846, from No. 250. 12 1848 from No. 251. 13 1850, from the first volume, No. 254. 14 1851, from No. 256. 15 (Styled Ryusho, the signature of the former Hiroshige II) 1867, from the last volume No. 254.
