Example of imagery in To Kill a Mockingbird?

One example of imagery in To Kill a Mockingbird can be found in Chapter Nineteen, when Tom Robinson is being sworn in for his testimony.

Thomas Robinson reached around, ran his fingers under his left arm and lifted it. He guided his arm to the Bible and his rubber-like left hand sought contact with the black binding. As he raised his right hand, the useless one slipped off the Bible and hit the clerk's table.
