French artist and photographer Francois Beaurain has an extensive collection of hand-painted movie posters from Liberia. These were mainly produced for video clubs in the 1990s, painted on plastic tablecloths, using the image on a VHS box.
Tablecloth was preferred to primed cotton canvas because it was thought more resistant (posters were nailed outside on any kind of support, exposed to the sun and the rain) and cost efficient. It was not an easy task to find the posters as most of the video-clubs have long dumped their piles of posters. Most of the posters found here were found in video clubs, usually under a mattress or nailed on the tin-roof to make the projection room darker.
Most of the paintings were signed by the artist. Some are better likenesses than others, but all are interesting for what they are. See some of these posters at Beaurain's website, and even more of them in a video. -via Everlasting Blort
