I recall old film posters used by movie theaters as advertising materials. They were displayed around the city when films were released.
Here is a film festival at Ann Arbor –World cinema film series. Nice nostalgic posters here ! I also notice the color selections through the years. From 1930’s to 60’s color choices got more graphic colors like black and white and muted tones. And one 1993 poster’s design is very different than the rest.
Below are the colors of small advertising brochures.
