This, the first book on the subject for over 20 years, classifies all known authenticated pot-lids by subject, lists their many variations and sizes, assesses their rarity and value and provides much new information on the history and contents. Errors and omissions in the earlier literature, many perpetuated through successive publications, have been corrected and the whole listing has been renumbered to avoid the anomalies caused by the absence of flexibility in the old system. Every lid has been measured so that all size categories can be accurately defined and rarity has been gauged as accurately as possible by an examination of nearly all auction catalogues from 1924-2002. For the first time virtually every item is featured in full-colour. The section on ware has been simplified and clarified and many previously unrecorded items are published for the first time. The floral sections have been extensively revised and extended.
