Spot the tiny urinal! These miniature reproductions of Marcel Duchamp's artworks were made by the artist himself, part of his 'Boîte-en-valise' series (French for 'box in a suitcase'). The box expands to display the tiny works like a portable museum, or like a travelling salesman touting his wares – it's thought to be a wry dig at museums' obsessions with collecting 'original' works of art. Take a closer look in our #DalíDuchamp exhibition – open until 3 January: https://roy.ac/2BIiAI3 | Royal A
