Supposedly, Rawdon was known as the "ugliest man in the British Army" (or "the ugliest man in England"). I only traced the comment back to 1914, so I don't know if it is truly contemporary or a 19th century label.

Either way, it cannot be argued that he was something less than handsome. That notwithstanding, his charmingly unattractive visage was immortalized on a large number of occasions -- a reflection, no doubt, of both his political importance and the foible of vanity which is mentioned by many who knew him. He was painted by both Reynolds and Gainsborough, as well as a host of lesser artists (James Atkinson, Martin Archer Shee, Hugh Douglas Hamilton, John Hoppner and others). His bust was modeled by Nollekens in 1810. He and his wife were even painted in Indian fashion by an unknown artist during his tenure as Governor of Bengal. John Kay and Gillray both immortalized him with caricatures in which he's always instantly recognizable.

My personal favorite of his many portraits is the whimsical one shown above, which was painted by Sir Joshua Reynolds in 1789 and now in the Royal Collection. (He's thinking, "Why is this big curtain thing billowing around behind me when I appear to be standing outdoors?") The Hoppner portrait, represented by the 19th century engraving below, is more indicative of how he's shown in most likenesses.
