This is Larkhill, at its junction with Regent Street, in 1913. I was born on Caton Street, which backed onto the shops on the left, in January 1958. Although this photograph was taken a good 45 year before I was born, it doesn't look much different to the Larkhill that I remember as a young child. The awnings outside the shops, the wide pavement, the elevated properties of Larkhill Terrace on the right hand side, looked just the same in the early 1960's. There would have been a few motorcars parked by the kerbside maybe, by the sixties, but not too many. I can even remember posters being pasted to that long wall at times.

The photo below is for the anonymous finder of the diary (please see the comments). Sadly it doesn't show the property that would have been 98 Lark Hill Terrace, as it would be just behind the photographer.
