Here's a photo of the entire original Samuel Loxton ink drawing, including the title, Hotwells, Looking across the river from near the Clifton Bridge station.
I bought this from eBay on something of a whim. I have no provenance for it, and the listing mentioned it was "circa 1910". It certainly seems to be (a) original, and (b) by Loxton. The very faded pencil below the picture seems to be very in keeping with Loxton's work: there are instructions for reducing the picture for print use, and I think a mention of the Bristol Observer, where Loxton's pictures were regularly published. It's very hard to make out the writing, though.
