Believe it or not, this is the stretch of Turnpike Lane between the railway bridge and the junction with Wightman Road.
It's so very changed that it's hard to believe I have the location right. In the comments below I've added an assembled collage of magnified portions of the image. On the right you can see a pub called the Unwin Arms. Below that, I've also added a photo from English Heritage with a verified picture of the Unwin Arms at 163 Turnpike Lane, on the corner of Haringey Grove. As you can see, it is unmistakably the same pub as the one in the main picture.
The first few houses in the distance were on the corner of Turnpike Lane and Hornsey Park Road. They were destroyed when the "Wood Green Bypass" was created; the taller ones just beyond them still stand today and are the ones you see as your approach the traffic lights along Wightman Road.
On the left is Salmon's artists supply shop - imagine that in Harringay today!
Just beyond the Unwin Pub was Harringay's fifth cinema.
You can see how much narrower Turnpike Lane was in this photo. It stayed the same until the 1970s when all the buildings on the right were demolished and the blocks of Council flats built, including Dylan Thomas House.
