Publicity pictures for the upcoming Season 5 of American drama series Downtown Abbey were released not long ago, and one photo in particular caught the attention of fans.
Can you spot what is wrong with this picture? Hint: It's a historical error.
A water bottle was spotted by sharp-eyed netizens in the background of the photo -- something that did not exist during the 1920s in which the television show was set.
The television network apparently removed the image as soon as it was discovered, but the 'damage' had already been done.
Not to worry though -- the cast of the show wittily responded to the careless mistake in good sport.
They posed for a group photo with all of them holding water bottles and posted it on Instagram, along with a link to charity foundation WaterAid's website.
Kudos to the cast for making use of the online stir to raise awareness for a good cause.
