From one of the three Blackpool piers (my money is on the South Pier), another walkie from Blackpool company Walkie Snaps. This is a pre-War example, identified by the film sprockets showing on the right hand side, their layout at the time. The print is 3″ by 4″ approx and would have been a strip of three. The two girls are enjoying an early afternoon stroll judging from the shadows, other holiday-makers are taking a post-lunch rest in the shelter on the left!
There is some history about Walkie Snaps on the site (although for such a prolific walkie firm not much is yet known) and more examples of their photos in the book Go Home On A Postcard.
