Flickr member Neil Poole took a series of wonderful London city images from the Shard. Most of them have window glass reflections but this one seems to be reflection-free. The white building is nick-named the walkie-talkie but you can see many other London architectural landmarks in this amazing shot.
I’m adding this second view in the same direction, zoomed back. It has reflection but it’s useful to get a context for the first shot.
