I love maps too, and I have several reproductions of local areas produced by Alan Godfrey Maps. They are interesting because on the reverse there is always a commentary. My map of Birmingham city centre in the early 1900s has a list of all the businesses- including a needlework school, a domestic servants agency, and several tobacconists. The map of the area where I now live, from the same period, shows the appalling density of houses, mostly in “courts” with shared privies and wash houses.
