Promo card for "Undressed Salad"?

If I make a black-and-white promo card for Undressed Salad, which model do you think I should feature on it?

Please don't suggest a model who's requested anonymity. (I've likely already made cards for them anyway!) Might be best to include a link with your suggestion, so I know which model you're referring to.

The game is about making card sets by shape or by color. As a fun twist, the game also includes four shapeless cards and four colorless cards. But as a promo card, I could make a card that is both shapeless and colorless!
