You know how last week a plastic water bottle ended up in a Downton Abbey publicity picture?
Well, this has appeared on the show's Instagram.
After seeing the reaction the picture caused earlier this week, the cast and crew came up with the idea of turning some of this attention towards an issue around water that really matters. They hope that by posing for this picture they will be able to raise awareness and amplify the work of international charity WaterAid.
