One of a dodecahedron's dozen (4)

Ross

I believe the answer is:

face

(Other definitions for face that I've seen before include "'Cheeks, mouth, eyes etc (4)'" , "well-known person" , "Confront - mug (slang)" , "Surface; visage" , "Outward appearance" .)

I've seen this clue in The Wall Street Journal.
