No, a cover letter is not always a advertisement, so it could be true OR false. But based on your question, I'd say true.

I believe it’s remembered
In the novel To Kill a Mockingbird, Atticus never has to
rethink his position on an issue. He is very level-headed all throughout. In
comparison with most of Maycomb’s citizens, he is the only one who is least
infected by prejudice. He is not racist as he goes to a black community to
deliver news. He also lets his children go to Calpurnia’s church. He doesn’t
have problems with the circumstances wherein his children are looked after by a
black woman.
