Well-known phrase or saying? The words on the card make up a 12-word phrase (including the definite article) that is certainly not a well-known phrase or saying. However, I will also accept other shorter and more familiar phrases (the most common of which is five words long, including the definite article). That said, the point of the answer is not that it is a well-known phrase, if you see what I mean.

Representative of a person? *some audience applause*     Taking this first as a narrow question, following on Raak's question before last, I would now amend my answer to say: Yes, The mineral piece does include a representation of an person. Thinking about the AOTC more generally, it depends a bit on how you interpret the word "representative", but the best answer is No.
