These posters of Alfred Hitchcock films by Laz Marquez are described as retro, or retro-modern. I’m not really sure - but only because it’s such a different aesthetic to Eric Tan’s (which has an Art Deco sensibility to it).

I suppose it’s the limited, repetitive palette - black, red, and white - that really evokes the ‘old’ style. Otherwise, the graphic concepts seem quite contemporary. The layering of the female silhouette with birds emerging from the hair, for instance, feels post Photoshop, not ‘retro’.
