Bauhaus artist Paul Klee is the subject of a major exhibition at Tate Modern.
The show features 130 drawings, watercolours and paintings from collections around the world.
Klee, who once described drawing as "taking a line for a walk", is best known for his abstract patchwork paintings of colour.
The curator of the exhibition, Matthew Gale, explained how they put the collection together.
