A new book appeared a while ago: Old Hong Kong - Kong Kai Ming Sketches (ISBN: 978-962-678-839-4) (http://www.cp1897.com.hk/product_info.php?BookId=9789626788394&cl=engli…) @HKD268.-, available in all book chains and smaller book stores. The book is full of sketches in great details in locations all over the city. Go grab one while stock lasts.
Thanks & Best Regards, T
