Whoops, a set stylist at the Downton Abbey made a major boo boo!

Shortly after this Season 5 promo pic was released, fans spotted a water bottle that was left in the photo be accident. The show is supposed to take place in 1924, so obviously they DIDN’T have bottled water back then.

Can you spot the mistake on the mantel?

Season 5 in America launches January 2015.
