Stormtrooper face

As I go on my usual lunchtime walk around the industrial estates of south west Leeds, I realise that I am scraping the bottom of the barrel so far as photgraphs are concerned.  However, in the tradition of objects that look a bit like faces, this one is a bit of a find; it is almost at ground level and was difficult to spot.

However, I thought the top bit looked a bit like a helmet and the faceless face a bit like a stormtrooper!
