I just came back from seeing the current exhibit at the newly opened Poster House in NYC, which bills itself as a poster museum. The show is about hand-painted movie posters made in Ghana for the local market in the 1990s, and it's really fun. I've always liked those posters, they have a naive, sort of folk art/outsider art quality that I appreciate. I recommend to anyone visiting NYC these days that they should go see this rather unique museum exhibit.
