Centre image - fake photo: You probably won’t notice anything out of the ordinary, even if you’ve visited the British city of Oxford and are familiar with the Radcliffe Camera in the foreground.
Left image - real photo: But this photo was taken in February 2018, the month that Oxford University’s Brasenose College flew the multicoloured LGBT flag on its roof. Brasenose College is in the photo’s background. Someone has airbrushed it out.
Right image indicate the missing flag.
