A painting of a nude form, a male, was seen on the Mosaic Investigation wall in Mark's flashforward.
This painting is by the French artist Jean Auguste Dominque Ingres. It is entitled Oedipus and the Sphinx and was painted in 1808.
Dyson Frost gave this picture to Charlie Benford and asked her to give it to Mark. On the other side of it was his list of demands concerning Demetri Noh.
