A promotional photo from the set of the PBS series Downton Abbey is making the rounds on social media at the moment, ever since a keen observer noticed that a plastic water bottle was left on a mantlepiece in a publicity photo.
As the setting for the program is currently 1920’s England, this is of course out of place.
Ever since it came to my attention though, I have been combing photos from the series, looking for similar mistakes. And I found a few! See if you can spot them too.
