The exhibition entitled 'Likeness and Unlikeness' is taken from Qi's painting theory that "The wonder of painting lies somewhere between likeness and unlikeness. Too much likeness would be fawning on the populace while too much unlikeness, deceiving the world." This was the very realm that spurred Qi on with experimentations all his life. The 80 or so works specially selected for the exhibition, primarily paintings with a supplement of calligraphies and seals, cover the artist's early and late styles illustrative of the different stages of his artistic development. The present catalogue includes foreword by Tang Hoichiu, preface by Yang Renkai, and chronology of the artist.

這次展覽的主題「似與不似」脫胎於齊白石的畫論，他認為「作畫妙在似與不似之間，太似為媚俗，不似為欺世。」這亦是他一生所追求及探索的境界。是次展出的80多幀作品大多為具題識鈐印的畫作，呈現了齊白石早年及晚期的風格，對於瞭解他各個時期的畫風大有裨益。書內亦載有鄧海超撰寫的前言、楊仁愷的序言及藝術家的創作年表。
