Vintage Girly pinups

Why is it that the women in these oldschool cheesecake illos always appear shocked, surprised, and totally unprepared to perform even the most mundane of tasks? The expression is, like, "Heavens! Someone's just crammed a red-hot poker up my butt!" I mean, take the image shown here, from Art Frahm. Maybe she's a midcentury bimbo wearing loose drawers, right? OR, maybe she's an undercover leet hacker and card-carrying MENSA member. Having just finished a phone phreak session in this public booth, she disguises her sinister, geeky hijinks with a bag full of carbs and a sight gag to divert that sneaky federal agent in black. "Smile now, narq," reads her invisibly eeevil thought-balloon, "1 PWN3D J00!" Anyway, here's an extensive online gallery of digital babes from yesteryear.
