Beautiful chinoiserie style tea cup and deep bowl saucer, Petrus Regout, made in Holland around the turn of the century. It's a demitasse size, saucer measures about 4 3/4" in diameter.
The design is red and dark green with a little mustard gold, pattern is called Pekin. There's no chips or cracks to either piece, but this does show wear and age with some scratching and discoloration.
