I didn't really think many of the covers were very good or did justice to the story. However, these two covers stood out as being different than all the rest. Instead of having an image of the mockingbird or of Scout, they represent the man in the story who was accused of the crime. This also represents the more abstract concepts of justice and prejudice, which are big themes in "To Kill a Mockingbird." I feel like these two covers might appeal to a more grown-audience than the others, a more abstract or human-centered viewpoint.
The jail cell cover is very simple, but the outstretched hand shows the need for compassion. Jem and Scout learn compassion through the people that Atticus defends and through his own actions.
The other cover is simply a face of a person looking down. To me this cover represents people that were discriminated against in Maycomb and other places like it; the fight between black and white.
While these covers unto themselves may not be very unique or amazing, they do stand out among the rest of the books for representing a different level of the story.
