I've got several Then and Now books, including:
"Birmingham Then & Now" by Mark Norton, "Central Birmingham Through Time" by Eric Armstrong & Vernon Frost and "Birmingham Up Town Through Time" by Mac Joseph, Ted Rudge & John Houghton.
All three are very interesting. Most of the "Now" photos are from 2009 and 2010. The "Then" pictures are from up to and before the 1970s.
