Poster for the New Romancecar Limited Express 

 The name “Romancecar” comes from movie theater seats. At a movie theater in Shinjuku, there were special two-person seats called “Romance Seats.” Since the limited express trains also had two-person seats, they were named “Romancecar.”

Since Miyanaga was originally a fine artist, his posters, instead of using photography, feature a heavy, hand-painted touch reminiscent of oil or watercolor. This gives his commercial work a distinct, artistic solemnity that sets it apart from typical advertisements.

At the center of this particular design is the streamlined Odakyu Romancecar 3000 series , which represented the pinnacle of technology at the time. Placed diagonally in a powerful red color, it strongly impresses viewers with a sense of speed and anticipation for the future. Beyond the train, the face of an exotic, Western-style woman is drawn large. This motif of the beautiful woman, true to the name "Romancecar," symbolizes not merely a mode of transport but an aspiration for a "romantic, extraordinary journey" and the Japanese public's desire for a modern lifestyle at the time.
