When it comes to images of Canis, otherwise known as William Duke of Devonshire, there is generally one that floats around on the web by Batoni showing the Duke on his grand tour adventure. And let's all be honest, most of you probably looked at it and went, "How did he get all that eighteenth-century tail?!" Which is a totally legitimate question being that the Duke lacked social skills to be smooth with the ladies. He just looks a bit plain and awkward. When Anton von Maron painted him at the age of 20 the result was also pretty bad.
But my favorite images of the Duke are the lesser-known ones which, ironically, are by one of the two most famous artists of the time, Joshua Reynolds. One shows how handsome the Duke was around the time that he married Georgiana. I believe the painting is in bad condition now, but you get a good idea from the print (love that coat!):
