From Bristol's Lost City, by Clive Burlton, available from Bristol Books; photograph from the author's own collection.
(And extra credit goes to my parents for buying me the book for my birthday! Thanks!)
The Bristol International Exhibition site, presumably around 1914 or not long after. You can see the Rownham Ferry in use, too. I still find it pretty amazing that there used to be a busy ferry and a significant railway station on this little scrap of land that I just used to know as the grassy bit at the start of the towpath, let alone a replica of Bristol Castle!
