we're still in Blackpool, but we may now be in the 1950s (or even the early 1960s). How I know we're in Blackpool is that you can see Louis Tussauds (the Blackpool waxworks) in the background. The chap in the front looks like he may have been working as conductor on the trams given his little shoulder bag, and I like his enamel tea can for breaks.
Here's the wiki link on Louis Tussauds and check out here to see a panorama of the street. (It looks like the panorama is from a couple of years ago as Louis Tussauds has now closed and reopened as Madame Tussauds).
I visited Louis Tussauds on a trip to Blackpool in the 1970s, I don't remember if I bought a guide book, probably not, or if I did it is long since gone, but I do remember it had an over 18 only section, which had lots of biological waxworks with diseased or deformed body parts (which of course I was too young to view).
