Question:

Art... What is the best symbol for a collage?

and why?

Best Answer - Chosen by Asker:

A diploma or a mortar board, because that is what you are going there for.
Or a candle, because you are supposed to be going there for knowledge to spread it.
But they are taking away my doctorate because I didn't use complete sentences and I ended with a preposition.
