What is an example of symbolism in the motion picture, All About Eve?

When Eve finally receives the award at the ceremony, it symbolizes everything she has ever wanted. Eve has worked hard to manipulate people and situations so that she could be recognized as one of the greatest actresses in the theater.

Eve's award also symbolizes Phoebe's attempt to rise in a similar way. When the film ends, we see Phoebe dressed in Eve's coat and holding the award in front of the mirror, imagining what life would be like if she also won such an award.
