Top marks if you can recognise and name the street in the main picture (do not read on if you want to play this game).
Relative newcomers to Portsmouth will be hard-pressed to put a name to it for it has long gone.
For a clue, look at the picture immediately inset of roughly the same view today.
Of course, it shows Market Way and the site of the now-flattened Tricorn on the left.
The old view is of Thomas Street, looking west, and it was taken in 1957.
It’s unrecognisable today and is an example of just how much the city has changed.
But those who want to locate themselves might just be able to make out the corner of Martha Street with the Brewery Tap pub on the corner. It was later renamed the Charles Dickens.
