In 1890, the second Sherlock Holmes novel, The Sign of the Four, was published in February, 1890, in America's Lippincott's Magazine. It was not illustrated, and there was just a colored frontispiece. Later that same year, it was released in England. Again, only a frontispiece was included. It was a scene of Sherlock Holmes and Watson at Pondicherry Lodge, with the body of Bartholomew Sholto slumped in a chair. :Look at the nose on Holmes!
However, to be fair, this drawing was much better than the ones done by D.H. Friston and Charles Doyle for The Valley of Fear.
