Is there a main character that the snowman is portraying and why? and is this character experiencing struggles of survival and acceptance
(Does this character experience struggles for survival and acceptance?
If the reader wishes to attach symbolism to the snowman that the children make, he/she may see that all the various citizens whom this snowman represents go into the whole of its creation. Likewise, all the citizens of Maycomb, black, white, upper class, middle class, lower class--all are part of the community, all are subject to the laws of nature, all are affected by what happens to the others.
Perhaps, the creation of the snowman by the children demonstrates that they--unlike many of the adults of the community--understand this interrelationship of citizens in Maycomb. Without this understanding, the people of Maycomb suffer the "disease common to Maycomb" of which Atticus Finch speakers. Consequently, the entire community suffers and certain elements in this community are destroyed as a result, just as the snowman suffers damage.
At first, the snowman looked like a Negro because the inside of the snowman was earth. There wasn't enough snow for the whole snowman. Then, it looked like Miss Stepanie Crawford with large hips and skinny little arms. Eventually, they packed enough snow around the middle that it looked too much like Mr. Avery down the street, especially with the facial features they added. Finally, Atticus pointed out thatit looked libelous, so they added Miss Maudie's gradening hat and hedge clippers. None of these characters, other than the earthen snowman experienced survival struggles. Each of the neighbors had their own vices. Miss Stephanie Crawford was a gossip and baked with liquor in the finished product. Mr. Avery was fat, and drank a lot. He also relieved himself off the front porch of the boarding house. Miss Maudie was a good-hearted soul who also gossipped. All of these were white characters firmly accepted in Maycombe society. Luckily the snowman's hat and hedge clippers were some of the possessions that survived Miss Maudie's house burning down.
