Hard to believe but apparently we’re still in the grips of a hosepipe ban. A permanent reminder sitting in your garden shed (next to your hosepipe) might prove to be a better advert for water saving than the current rash of posters.

I’ve calculated that one 48 sheet poster for one month in a half decent location could buy about 833 units.  So in this instance the medium is indeed the err… message.

*£2,500 / **£3 = 833 units
