Tezuka's heroine bats her eyes at crime reporters
BY MARIKO FURUTA THE ASAHI SHIMBUN
Osamu Tezuka sketched the heroine of "Ribon no Kishi" and a self-portrait on a wooden ceiling panel. (SHINGO KUZUTANI/ THE ASAHI SHIMBUN)
A framed wooden ceiling panel sits in the press club inside the Metropolitan Police Department's Ikebukuro Police Station in Tokyo's Toshima Ward.
It shows a sketch of the heroine of Osamu Tezuka's manga "Ribon no Kishi" (Princess Knight), and a self-portrait of the artist in his inimitable style.
As the anecdote goes, Tezuka (1928-1989) drew the pictures on the panel, which measures roughly 70 centimeters by 30 cm, after removing it himself from the legendary Tokiwa-so apartment building, where he and other manga artists had once lived.
