From a publication of three hand-bound volumes of 36 bird illustrations, later followed up with a supplemental set of volumes in 1884. Note the original binding holes along the left-hand margin.
Edward Strange wrote of Bairei's three-volume publication of bird illustrations, "...perhaps the best illustrations of bird-life ever cut on wood. They are printed each from six or seven blocks, the shading even of the drawing being to some extent thus provided for, instead of having been left to the skill of the printer." ("Japanese Illustration: A History of the Arts of Wood-cutting and Colour", Edward Fairbrother Strnage, London, G. Bell and Sons, 1897, pg. 105)
