Great book! I bought this about a year ago, and it has been so useful. I've been able to take it around with me to Antique fairs and junk shops, and the accurate information about identifying and dating Deco ceramics has been a great help.
Lots of colour pictures, and a better than usual introduction, but the best thing is the book gives space to some lesser known factories such as Langley, Enoch Wedgwood, Shorter, Johnson Brothers and Myott. Also the usual stars such as Clarice Cliff, Susie Cooper and Charlotte Rhead are here. Also my favourite, Keith Murray.
I only wish it was longer!
