Why not just say movie posters from Ghana? What is connection between these and the concept of African, I wonder?

Anyway, I'm Ghanaian, and you can AMA. There's a lot of such art, many on walls of the erstwhile movie houses. Most of them are very realistic and collectible, but I guess only the garish ones command attention and so are easier to make into a story.

As a kid I once watched an artist paint one of these on a wall in a few hours, was very cool.
