A: Dishes featuring the busy Sun Bonnet Babies are very popular with collectors. The figures are charming and radiate cheerful enthusiasm that is irresistible. The mark you enclosed was used by Warner-Keffer China Company. They were founded in 1908 and made semi-porcelain in East Liverpool, Ohio. The babies' faces were covered with puffy bonnets, and several potteries in the United States and Europe decorated their ware with the happy images. By 1912, Warner-Keffer China Company was out of business. Your circa 1908 tea set would probably be worth $175 to $275.
