Picasso’s “Old Guitarist” hides a past life of a former painting.

The Art Institute of Chicago x-rayed the painting to reveal the menagerie image underneath of a woman, child and animals.

The Illinois Institute of Technology, in conjunction with the Chicago Council on Science and Technology and Argonne National Laboratory, hosted a crossroads event Wednesday, bridging the art and science of understanding Picasso.

Art Institute of Chicago conservation scientist Francesca Casadio and painting conservator Allison Langley combined art analysis and scientific techniques to bring to life Picasso’s creative methodologies -—secret pictures hidden beneath familiar masterpieces and the mystery of his artistic mediums.
