This is Salvador Dali's oil on canvas painting called "The persistence of memory". Created in 1931 and now it is at the MoMa in NYC, it is considered one of his most famous works. Dali used faint brown, yellow and blue colors in this painting. The meaning of the painting is up to interpretation, some believe it is about the non existence of time during sleep only memories, and some believe since Dali was also a philosopher that it is about Freud's psychoanyalis. Dali called his paintings hand-painted dream photographs.
