Ancient Chinese Song Dynasty Terracotta Tile with Trio of Figures

An Ancient Chinese, Song Dynasty, terracotta tile. The relief features three figures and a vertical black band painted on the left-hand side. The figures represent a father, mother, and child. The father figure wears a red garment and holds an offering in his hands. His hair appears to be styled in a small high bun, and his face features prominent eyebrows painted with black pigment. To the right, the mother figure, in a yellow garment, is hunched over, carrying a child on her back. Her arms are crossed in front of her chest with her hands clasped together. The child has a large high bun and is wearing a blue/grey garment. The whole piece is square in form and the background surface is plain grey. On the reverse is a textured grid pattern which would have allowed the tile to attach to a wall more securely.
