Here is a picture of an example of a way sign directing you on where everything is if you needed help. This sign is from Richmond, which is in zone 4 near the most scenic and country side area in London. I liked this way sign because it pointed you to the directions of the specific destinations you wanted to go and even gave you the distances from where you were standing. Very helpful way sign in Richmond. The only problem is that I had was that I wish the sign would of been yellow or something brighter to stand to a little more instead of black.
