I was very fortunate to visit the amazing city of Havana a couple of years ago. There isn't much folk art for sale in Havana. It isn't a stuff-oriented culture like ours! Most folk art is in neighborhood environments -- blocks of murals and sculpture created by the residents helping with a project envisioned by a neighborhood artist. But I searched Havana markets and found these pieces.
Materials are scarce, like everything else. Paper is recycled and much is made of paper mache. (We visited a school where even the play kitchen in the small children's area was made of paper mache. Yes, even the stove and refrigerator! Cubans are very resourceful and creative people.)
