1920年代に製作されたという古典作品から戦後のブームで国内製作された裏物ポルノの歴史を紐解く映像集。寸劇じみたセックスシーンは今となってはおとなしく見えるが新鮮。当時の流行や取締りとの戦いなど、ポルノ史の資料としても面白い。This is a collection of videos that unravels the history of backstage pornography、 from the classic films produced in the 1920s to those produced domestically during the postwar boom. The skit-like sex scenes seem tame nowadays、 but they are fresh. It is also interesting as a source of information on the history of pornography、 including the trends of the time and the battles with the police.
