That is an interesting photograph. I have no idea where it is, but I also think it's a private mansion rather than a pub or public building. If you look at the man in the first photo it almost looks like he was photographed as he was casually walking by, the pipe in mouth and newspaper tucked under his arm. The second photo looks more posed the pipe is in his other hand, the newspaper in now in his jacket pocket and he is positioned with a grand building in the background. He may also have removed his glasses for the second photo. Going by the shadows I'd say the photo was taken around midday. The man's face is on full shadow under his hat and very narrow shadows on the building indicating the sun overhead.
Also perhaps a family snap, as a professional photographer, (and there were many around in the street taking photos of the public to earn a living. I have photos on both sides taken by street photographers) would only take one, film was not cheap, and perhaps not offered the first for sale as it is not as good as the second.
Barry do you know who the man is? And do you know where he lived? That may help narrow the location down. He looks to be in his 50's that might help in a timeline location.
