Picasso: Painting as "Sum of Destructions"

" 'What comes out in the end is the result of the discarded finds.
"~ Pablo Picasso

"Pablo Picasso (1881-1973) often left visual clues on the surfaces of his paintings to suggest a hidden image underneath, as on The Tragedy of 1903. Artists frequently make changes to a painting or reuse a canvas or panel with an image...."

This is an interesting take on Picasso's paintings. Apparently, he didn't re-use canvasses several times (only) to save money, but as a part of his creative process.

Presumably whoever is writing for the National Gallery of Art has both oars in the water - so this is quite an interesting insight into how Picasso worked.
