Published in 1949, this is a very large heavy cloth bound volume containing fifty-two ordnance survey maps of Derbyshire. The covers are printed stating sheets 38-60, these are actually printed on 52 individual maps, not the 22 implied by the cover. The book measures 23 inches by 17 inches approx. (59cm by 43cm) There are handwritten annotations to many of the maps, mostly short mauve ink lines drawn with some numbers. The index map at front notes that these mauve lines indicate footpaths, These maps were marked up with the “National Parks and Access to the Countryside Act 1949” to indicate were access footpaths are located.
