This is persuasion by pointing out what others have done. It is the persuasion of example; an appeal that is dignified and inspirational.

This will enable you to test it out thoroughly and, furthermore, you will not have to make the first payment until you have opportunity to make collections for the December advertising. This proposition must be accepted before Oct. 31st."
