The home shown in this postcard still stands, as you can see in the picture below, which I took just this week. It is located at the southern end of South Street, just past Penzance Road. Note how much the trees grew in the century that separates these two pictures.
I assume this was, at the time, a summer cottage and that the name, “The Billingsgate,” was given to it by its owner. It was common for well-to-do owners to give their summer homes a name. I have not been able to find any reference to it using that name.
This postcard was mailed in 1913. It does not identify a publisher or a publication date. The style of the front and the markings on the reverse suggest it was from the same publisher as this 1911 postcard of the railroad station.
