The Downing Street Facebook page changed its profile picture on Monday afternoon to one of David Cameron wearing a poppy.
Writing on the Facebook post, Danny Burchell commented: "Would've been quicker to just take a new pic instead of Photoshopping a poppy."
Indeed, there are lots of pictures of Cameron really wearing a poppy out there.
As some journalists pointed out, imagine if Labour HQ had made the same oversight with a picture of Jeremy Corbyn...
So what's going on?
Update: The photo has already been changed
A Downing Street spokesperson told The Independent: "It was just an oversight."
