This is all fascinating stuff. The book was produced as a result of the new 1947 Town and Country Planning Act which was the beginning of the current development planning and development control systems. These early documents tend to be much more informative than the sort of things produced nowadays. They were starting from scratch, so they described the area being planned for, with lots of interesting photographs and often gave a lot of history as well. Potential for various improvements was usually described, sometimes with many artists impressions. Several of the captions are expressed in terms of potential improvements. There would almost certainly be a copy of this book in the county archive covering the Wirral. I have seen copies turn up for other areas in second hand bookshops, they are evidently not particularly common though. You are lucky to have one for your area, thank-you for sharing it here.
Hi, Toby, I hadn't realised this was part of a national project. I have a pristine copy of this book, complete in its original slip case, which I acquired several years ago. I may try photographing sections of the large fold-out map.
