Fagin has of course a hook-nose in Cruikshank's original illustrations to OT; & such was particularly prominent in Alec Guinness'a make-up in the 1948 film, and to an extent tho not quite so caricatured, Ron Moody's in Oliver.

But I do not remember this feature being actually mentioned by Dickens in the novel. I take it that it was just assumed that Jews would have this feature. It will certainly be found in all those charming Punch cartoons up to about the 1920s.

Many Jews have this feature, of course; but by no means all. Not prominent e.g. either side of my family.
