 Instagram owner Facebook has reversed a ban on a poster for Spanish director Pedro over his new film showing a nipple producing drops of milk. Jair Vardruna, who designed the advert for Madre's Paralayas, has said that the platform should be ashamed for its censorship. The social media company has now apologised for removing the poster. Facebook said it had made an exception to its usual ban on nudity because of the clear artistic context. The film, which will open the Venice Film Festival on 1st of September, stars Penelope Cruz as one of two women whose path crossed in hospital as they prepare to give birth. The promotional image was made to look like an eyeball producing a teardrop. A Facebook spokesperson said they initially removed several instances of this image for breaking the rules against nudity, however made exceptions to allow nudity in certain circumstances, which includes when there is clear artistic context.
