舊香居是台北一家悠久而尊崇的古書店，他們在佐伯俊男先生晚年時候結識他，並於2016年舉辦佐伯在台灣的首次個展。
2019年，舊香居再次為佐伯先生舉辦個展，並合作出版畫冊。這次展覽與出版，佐伯回溯到1970年，從他藝術生涯第一本作品集《佐伯俊男画集》重新發想，為當年這自費出版、限量僅500本的首作重新上色，取名《万象回帰》，意味世界萬物回到其根本。2019年佐伯先生辭世，這部跨越半世紀的著色，頓成遺作。
《万象回帰》每本附藏書票，鈐佐伯印章，印文「俊男」，手寫編號。
Jiu Xiang Ju Books is a prestige antiquarian bookshop in Taipei since late 1970s. They have been friends with Mr Toshio Saeki in his later years, and have organized Saeki’s solo exhibition first time in Taiwan in 2016.
In 2019, Saeki did another solo exhibition in JXJ Books Gallery, and published this major book Banshou Kaiki. This time, he returned to his very first book Toshio Saeki Gashu, self-published in 1970 in limited 500 copies, and colored the whole series for the first time - Taking the name “Banshou Kaiki”, meaning all majestic and myriad things return. Mr Saeki passed away in late 2019, aged 74. This coloring over half a century, has become the final re-touch of his life.
Each book of Banshou Kaiki is numbered, and comes with an ex-libris with Saeki’s stamp.
