Pablo Picasso
The Old Guitarist

The Old Guitarist is an oil painting by Pablo Picasso, which he created in late 1903 and early 1904. It depicts an elderly musician, a haggard man with threadbare clothing, who is hunched over his guitar while playing in the streets of Barcelona, Spain. It is on display at the Art Institute of Chicago as part of the Helen Birch Bartlett Memorial Collection.
At the time of The Old Guitarist's creation, Modernism, Impressionism, Post-Impressionism, and Symbolism had greatly influenced Picasso's style. Furthermore, El Greco, Picasso's poor standard of living, and the suicide of a dear friend influenced Picasso's style at the time which came to be known as his Blue Period. Several x-rays, infrared images and examinations by curators revealed three different figures hidden behind the old guitarist.
