These delightful Mahjong Flowers seem like folk art to me. They are well carved, but the images are very simple. Although it is hard to know exactly what birds and bugs are seen on the tiles, there is a very faintly visible butterfly on the Red 1, more visible on the Red 2. Birds appear on the Blue 1 and 3 and Red 3 and perhaps 4. I must confess, I love the Blue and Red 4s, although I have no idea what insects or creatures they are!
