I'm looking to license a model of a mad magazine-style Einstein caricature. Initially the model will be used in static images such as an application icon and a splash screen. Ideally, the model would look something like:

It is not crucial that the model be of Einstein, exactly. What I am really going for is a professor or other "recognizably knowledgeable" figure.
Any help referring me to a suitable model or artist is GREATLY appreciated.
