Only the most perceptive people can spot the mistake in this picture

The internet is full of pictures in which you are challenged to find the hidden mistakes, objects or creatures and this photo is no exception.

This challenge involves a picture of what looks to be a study or an office. It recently went viral because, despite how obvious the mistake may be, very few people have managed to spot it.

In the picture, you can see a table with a laptop, a telephone, a mug, a mouse, a calendar and what looks to be a printer. You can also see part of a chair.
