The concept is old, I thought of it about the same time I made my first illustrations of this kind, but I just wasn’t able to make it. I hadn’t found a picture of Marlon Brando as Don Vito Corleone that helped in the process, besides I think at the time I was trying to use the whole quote (“I’m gonna make him an offer he can’t refuse”), so I gave up (which proves that, despite what it seems – after all, the impression it causes is that it’s possible to fit any phrase to any face making the proper warps – this kind of optical illusion is very hard to do… and among the few times it can be finished, only a few look really good… In my case, for example, I think the only perfect one I’ve made was “Why So Serious?“) . But yesterday something made me remember the idea, and then I miraculously found the perfect picture, full of shadows, and then I made a sketch that today, almost now, has become the image I’ve just showed.
