This is a small, 8cm tall, vintage 20th century, powder blue glaze over white china bowl that was made by the English firm of Moorcroft for Liberty's of London. Usually Moorcroft wares are also hand decorated with floral surface designs. The powder blue glaze wares are part of a breakfast dining set. They were first produced by Moorcroft in 1913 for the tearooms in the Liberty of London flagship store. The impression stamp on the underside was not fully punched and it is obscured. Recently an 11 piece powder blue glaze partial breakfast set sold for $40USD (55AUD) at auction in January of this year in 2014 a 13 piece set sold for $130USD (175AUD). The estimate for the single bowl here is based on actual recent past recorded auction sales of matches. Retail 'asking prices' can be higher and vary.
