Sometimes a movie's marketing team knows when to market the movie itself and when to market the star. That this design for Preston Sturges' Sullivan's Travels is merely advertising the fact that Veronica Lake is in a movie though is not what makes it so great. There are plenty of movie posters (and a quite a few for Veronica Lake films fyi) that merely splash their star on a poster and expect people to see it, but with this Sullivan's Travels poster they have given her a striking eye catching design with big bold colours and given Lake a unique sexy charactature design.
Sure, you get no idea what the movie is about, but the focus of the poster is so magnetic that it doesn't matter because the poster has already roped you in.
This poster gets bonus points for realising the advantage of the colour yellow. It's done wonders recently for the posters of Kill Bill Vol 1 and Little Miss Sunshine too.
