The candidates (from top): Mary Pickford, Tallulah Bankhead, Jean Harlow

Interesting, if only for the shared name, "Mary"... but definitely not.

She's awfully close. Very similar facial proportions, and prominent enough cheekbones to cast the shadows shown on the sandwich, but...

...I'm afraid after analyzing Jean's face, she's the clear winner. Facial proportions are exact, angle of cheekbones, shape of jawline. Dead ringer. Some poor casino bastards paid $28,000 for a Jean Harlow cheese sandwich. I wonder if they can get the seller for misleading them with all that Virgin Mary crap?
