Ieoh Island (Dir. Kim Ki-young, 1977) lobby card. In the analog era, movies were largely promoted through posters, brochures, and film stills. In particular, a still in the same format as this material was called a 'lobby card' in the industry, which was printed with the title and major credits along with the representative film still of the movie and distributed to the theater, and the theater attached it to the lobby in front of the theater. It was used to attract the audience.
