It is not a portrait - in fact it is said to be really a "random" selfie by an macaque messing around with an smartphone or tablet or digicam or something like that.
There was a huge quarel going on about the copyright because an animal rights organisation claimed the macaque is the creator and not the human owning the camera and they won in court ;) !
So the Macaque is the owner of all rights on this picture...
Anyway the animal rights organisation did an appoinment with the man owning the camera (a british photographer I guess as far as I remember) so that he gets 25 % of all money raised throug the pic and the macaque respectively the animal rights organisation gets 75 %.
As I got the picture from a platform providing cc0 content I do not have to worry about the license too much ;)
But If I become a whale here on Steemit.com of course some beneficial gos as well as ngos will also profit of that ;)
