“In the past the mood of the comic postcard could enter into the central stream of literature, and jokes barely different from McGill's could casually be uttered between the murders in Shakespeare's tragedies. That is no longer possible, and a whole category of humour, integral to our literature till 1800 or thereabouts, has dwindled down to these ill-drawn postcards, leading a barely legal existence in cheap stationers' windows. The corner of the human heart that they speak for might easily manifest itself in worse forms, and I for one should be sorry to see them vanish.”
