And before you say "Ugh, but art museums are soooo boring..." A) I disagree, and B) this isn't your traditional stuffy, highbrow art museum! There's a world of difference between fine art and folk art.
Folk art is produced by common, everyday people, and is typically made for a utilitarian or decorative purpose. Folk artists make objects primarily for use in their own homes or communities. This can be toys, miniatures, keepsakes, religious items, decorative items for the home, or even ceremonial items for use in local holidays or traditions.
Folk art can also teach you a lot about other cultures. Every part of the world makes different sorts of objects and has their own unique artistic styles. So it's easy to see and appreciate all the differences (and similarities!) between various cultures simply by looking at their folk art.
The wonderful thing about folk art to me is that it is accessible to everyone. Anyone can look at folk art and understand what it is, why it was made, and what it was used for. Everyone can relate to it. And since this is, after all, the world's biggest museum of folk art, so there's plenty here to satisfy everyone's interests!
