The comic history of Rome (1852), A. Beckett & Gilbert Abbott, can be found at the Internet Archive (free subscription required for multiple reading)
Other Wikimedia Commons busts, paintings, and another caricature of Cicero can be found here. I especially get a kick out of this medieval view, he looks kind of anguished:
