How did Pablo Picasso celebrate his 80th birthday? Thanks to recent efforts by the Associated Press and British Movietone to make their newsreel archives more accessible to the public, we can now witness snippets of the occasion. The two companies announced a project to upload over one million minutes of digitized film footage to YouTube, comprising over 550,000 videos dating as far back as 1895. There are plenty of art-related clips to explore — watch New Yorkers in 1995 react to Christian Boltanski’s “LOST: New York Projects” in the subway or see Christo and Jeanne-Claude unwrap the Reichstag — but one of the greatest gems is the documentation of Picasso’s birthday.
