In the scene in the GF3 before the Massacre. Micheal was sayin how joey Zasa is the best dressed gangster and how hes famous. I think he was mocking Zasa, hows he wants to be famous but how the old dons never wanted to be known by everyone as a gangster etc.
I think it also kind of symbolic of how it was in real life. How the new style dons were very different then the old.
