And of course we have that memorable portrait of Winston Churchill by Karsh, which conveys the impression that Churchill was a bit of a bulldog.
There's the rub: we assume the attitudes and makeup of the bulldog because that's what reputation taught us.
Remove the identity and myth, and you are faced with a slightly over-processed portrait of a somewhat fat old man with quite a degree of degeneration writ large.
The production suits purpose because we have this well-established characterisation provided along with the visual. We didn't start with a cipher. Had Winnie just been the local vicar, looked like that and was shown like that, heads would probably have rolled, and Mr Karsh might not have been paid.
