Explanation:

The "celebrity or beautiful people" propaganda technique uses well - known figures to persuade. Joe Louis is a famous boxer (a celebrity), and his advertisement ("This World War II advertisement shows the famous boxer Joe Louis with the caption 'We're going to do our part'") uses his celebrity status to encourage people to join the army. The other ads: Uncle Sam is a symbolic figure, the British man is not a celebrity, and the Air Force officer is a professional, not a celebrity used for this propaganda technique.

Answer:

This World War II advertisement shows the famous boxer Joe Louis with the caption "We're going to do our part"
