Poster design
A hard-edged, hand-painted portrait of a delinquent youth brandishing a switchblade dominates the composition, set against bold tricolor panels of blue, yellow, and white. A reclining nude anchors the lower field, while the sweeping red brush title 「性春の悶々」 runs vertically at left. The green credit block touts 井筒和生・処女作品 and 三上寛 主演, with a cheeky side-snipe tag completing the classic Shōwa-era pink-film aesthetic.
