The internet goes down weird and wonderful paths sometimes, and one of these is The Composites. The project by Brian Joseph Davis uses commercially available police composite sketch software to create images of literary characters. The only qualification is that the characters have to be thoroughly described.
The image of Dracula above came from these descriptions in Bram Stoker’s 1897 novel of the same name:
A tall old man, clean shaven save for a long white moustache…His face was a strong, a very strong, aquiline, with high bridge of the thin nose and peculiarly arched nostrils, with lofty domed forehead…His eyebrows were very massive, almost meeting over the nose, and with bushy hair that seemed to curl in its own profusion. The mouth, so far as I could see it under the heavy moustache, was fixed and rather cruel-looking…For the rest, his ears were pale, and at the tops extremely pointed. The chin was broad and strong, and the cheeks firm though thin…The blue eyes transformed with fury. (Multiple suggestions)
