Where on the Tube?

One of my favourite photo sharing sites (not hard to guess which one) runs a group where you have to guess where certain shots in London were taken. I'm not sure how often London Underground related ones are featured but I love the picture from Mags below


Have a guess at where it is (easy if you search), but more importantly any guesses as to who or what Stanley Hunt Ltd did or do?

And just in case that's too easy. Where did I take the picture of the following clock?
