 This is a rare bird-shaped button lid with three birds. The central bird is on a three-sided openwork leg and is slightly bent forward. Both sides of the back are flattened and expanded with dotted rows of patterns to represent wings. The two birds on either side have flattened bodies without pedestals, and the upper surfaces are decorated with dotted rows of dots.
