Dr. Jarvis's daughter, Pam, gave me his two leather-bound notebooks. One on his humor notes (psychology mostly) and the other on the notes he used while speaking on the circuit. Hand-typed, they show his observations and corrections over the years. For anyone wanting to speak as a professional, these show his careful attention to each of his talks. Really interesting to follow while listening to his talks. These notes are for real students of humor and worth revisiting often as you study Charlie's skills and approach to presenting.
