Is there any form of art where you combine the facial characteristics of two people to create one person?

Answer 1

Well I guess you could maybe say cubism. Especially some of Picasso's portraits. Even though its technically not the purpose of cubism.

The only other thing is just morphing that's often done with film, like that 'Black and white' Michael Jackson music video.

Answer 2

portraits done like that take the 1/2 young face and morf it into the aged version of the same person but I don't think it's called anything in particular as far as form goes...you just do it.

Answer 3

Yes, it is done in fiction writing all the time.
