It's amazing how that image looks nothing like Hayworth.
How something is expressed, via the written word, is everything as we know (texts, emails etc). And was was mentioned afterward, Hayworth's depiction is an Australian artist's interpretation. That being said, I think many will agree that there are a lot of daybills that have been created wherein the actor depicted looks almost nothing like the actual person. The flip can also be said of many others, where a particular artist nailed an actor's visage, spot on.
Like any kind of art created, this is also an aesthetic POV, since a daybill, such as the one shown here, may, to many, look JUST like Hayworth, and to others, (like Louie), she will bear no resemblance at all (aside from that classic pose).
