The latest pillar box topper…

I’m not sure what the theme for this topper is but the component parts are tiny so it must fit Tiny Tuesday though it’s doubtful that it fits the mechanical bit.
I took this pic when I was on my way to catch the bus to the hospital so didn’t have time to check around whether there was something to give a clue to the theme. I already had to ask one man nicely whether he would move over slightly so he was either part of the pic or not in it. He went off so clearly didn’t want to be a star of Blipfoto. Can’t imagine why!
