I have a book called 'London's Lost Riverscape' which has a photograph of Cottons Wharf taken in 1937. The PLA sent a photographer to photograph the Thames riverside (both sides) from London Bridge to Greenwich, taking photographs from the opposite bank, each photograph connecting with the next to form a montage. These were published in the above mentioned book. If you can find a copy its well worth studying. There is no sign of an ISBN number, only the reference CN1481, the book was published in 1988 by Guild Publishing, authors Chris Elmers and Alex Werner.
