Each piece featured is a numbered edition, and marked accordingly on the base. These numbers are never repeated. Additional appeal for the connoisseur comes from the fact that numbered edition pieces also carry the designers’ signature fired underglaze, as well as the informative array of Moorcroft markings. Numbered edition pieces of Moorcroft are made to order, which means that the number made will vary with each edition. Numbered editions can sometimes be limited by reference to a period of time during which they are available.
