Producers of Downton Abbey have been left red-faced after a modern plastic bottle appeared in a promotional photo for the costume drama.
Perched on a mantelpiece behind Hugh Bonneville and Laura Carmichael, the bottle was spotted by eagle-eyed fans when the image was posted on Instagram.
Plastic bottles were not in wide use in the UK until the 1960s - 36 years after the new series of Downton takes place.
The image was later removed from Instagram and the ITV press site.
It was bound to happen eventually. I mean, there are like behind the scenes photos of these guys keeping their iPhones in their costume's pockets and whatnot.
Probably it was on purpose, just to make headlines. For sure after choosing one of many pics, airbrushing and photoshoping it, someone saw it, but left it for the sake of creating some talks about it.
