This is a vintage china teacup and saucer.
They are white with gold gild trim and pink, yellow, and blue flowers. On the back is a black "H" mark with what appear to be pheasant-type birds.
The saucer measures about 5.5" in diameter, and the footed cup measures about 3" tall, 4.25" long including the handle, and 3.25" in diameter.
These pieces are in good pre-owned condition.
