I call it goofing around. By Picasso, I grant you, but goofing around nevertheless. The Picasso Museum in Paris received its collection in lieu of estate taxes. I think Picasso got one over on the Republic. While there are some very beautiful pieces of art in the museum, which is housed in one of the grander mansions in Arrondissemont 4 in Paris. How so? By giving them a lot of his studies and experiments in form and composition, rather than final pieces. Please don't get me wrong - I think it is all fascinating. But, the studies are interesting not as art per se, but as windows into the evolution of master works. And, I wish the interpretive material (which, at the Picasso Museum, was in English) called this what it is - formative work rather than summative.
C'est la vie!
