What’s this all about?

OK, so I was in a small town close to where I live yesterday, paying bills and voting and all that really exciting stuff when I decided that to make the day seem a little better I would go to the local pub for a pint of good old Broadside.
After getting all the ‘parting with my money’ things out of the way I headed toward the pub and noticed this sign. I had never noticed it before, so I’m not sure if it’s been put up recently or maybe I just walked around with blinkers on previously.

Anyway, what’s this all about? Hmmm!
