Africa had it's fair share of military dictatorships during the 1970s and ’80s. They restricted importing large scale offset printing presses – which were a necessity for movie poster production. Instead, African artists - some of whom hadn't even seen the movies - were asked to paint movie posters.
Ghana provides many of the examples. “If the movie was gory, the poster should be gorier (skulls, blood, skulls dripping blood). If it was sexy, make the poster sexier (breasts, lots of them, ideally at least watermelon-sized)”, Frank Armah, one of the artists, told The Atlantic. The only restriction was that the poster had to fit on the side of a 50kg flour bag (or two sides stitched together). Today, these posters are considered to be art pieces, and expensive ones at that, with prices up to $15.000!
