An artist sneaked an AI-generated print on to a gallery wall before bemused visitors alerted museum staff. The print was hung up at National Museum Cardiff by secretive artist Elias Marrow, who said his Empty Plate piece - depicting a young boy in school uniform holding a plate - was viewed by a few hundred people before it was removed. One visitor who noticed the artwork asked a member of staff about it, but said the museum worker admitted they had no idea about the piece or when it arrived. An Amgueddfa Cymru spokesperson said: An item was placed without permission on a gallery wall in National Museum Cardiff. We were alerted to this and have removed the item in question.
