"I had selected his features as beautiful. Beautiful!—Great God!"

   The physical appearance of Frankenstein's 'monster' is at the heart of the novel, the fear and disgust it inspires in others being the main reason he becomes a monster at all.  A fairly complete picture can be assembled from  Frankenstein's descriptive glimpses but, as he discovers, it is only the sight of these elements combined in a living, moving being which renders them insupportably hideous.  Artists, playwrights and filmmakers have produced a wide variety of depictions over the years, some more faithful to the novel than others, but all sacrificing one of its central ambiguities: the reader can never directly observe the creature's monstrosity, only the prejudice it provokes in others.
