The time-travelling blooper spoiling this Downton promo pic.

 Can you spot the huge mistake in this shot?

There’s something in this Downton Abbey promotional shot that has ruined the entire 1920’s Britain theme.

Have a look:

Did you see it? There's a plastic water-bottle on the right of the mantle piece, which we're sure wasn't meant to be part of the scene, because that plastic bottle is there 40 years too soon, having not being widely used in the UK until the 1960s.

Fans of the show noticed the error, when the image was distributed in anticipation of Downton Abbey's return in January.

Ooops! Awkward.
