Japanese video of a man demonstrating the interior illustrations of the rare "Bruce Lee Movie" manga by Hisao Hayashi
That Japanese guy is Imai san, a super BL fan and the owner of bldvd.com, selling all BL's stuff.
At 1:03 min of the clip, it tells about the GAME manga. Would love to see the content.
I collected 70s HK and Taiwanese BL's movies & related comics but 've to admit quality wise, the Japs' are better back then.
