Hat Block - Head Size 53.5cm, Height 10.5cm (The bottom is marked "M", and it is believed to have been made about 100 years ago, so it has shrunk considerably.) This size is surprisingly useful for those who make hats. There are cracks, but they shouldn't affect use. If you are concerned, you can smooth them out by filling them with stone powder clay. Also, how about using it as an interior accent for those who like vintage items?
