I had seen this sometime back and had wondered. People were joking about this I think. As I was lying down today, thinking about life and self, I got reminded of this. And today I do understand the underlying concept truly. I don’t know if it was Picasso’s concept - pardon me, I have not looked up his thoughts on any of those paintings. I believe that experiences of a person alter his so called image in time. It’s truly with time and experience one realizes that there is no image, no persona - just a mixture of parts and roles and thoughts and experiences one has had. There is no image that can be called as just this one. Entropy increases with time and the concept of self expands to remove the boundaries. There is just a bundle of interesting and strange experiences. So much so one cannot recall how it was to be anything at any given time in life. So his self portrait at 90 does seem correct and plausible. In fact it is the only thing that makes sense: one lifetime of different experiences that could be almost called different lives - none or all of them - that one can relate to.
It is great to be alive.
