Bichromic posters
Posters are usually printed in 4 colours cyan, magenta, yellow and black represented by the CMYK letters. I started to collect Nollywood posters while I was living in Liberia, my favorites posters are the ones with printing issues, usually with only two colors. Here is a sample of my collection.
