On The Embankment, this 1924 woodcut by Charles Ginner, is up for auction shortly and a very nice thing it is too. Given that Ginner was London based and a prime mover in the Camden Town School, I’m assuming this is the Thames, but I can’t quite place that view.
Postscript: Thanks to @metrocentric and @sorbus for spotting that this is the arch at Temple, before it was largely filled by a monument to King George V in 1935.
