Documenta 12 is like a big art event where lots of artists come together to show their artwork to people. But not everyone can go see the artwork in person, so the people who organize documenta 12 make magazines to show pictures of the artwork and talk about it. The magazines also have stories about the artists and why they made their artwork. It's like looking at pictures of toys in a catalog, but instead of toys, it's pictures of artwork in a magazine!
