Which war advertisement uses the celebrity or beautiful people propaganda technique to convince people to join the army

The correct answer is the following.

The U.S. war advertisement that uses the celebrity or beautiful people propaganda technique to convince people to join the army is the boxer Joe Luis saying "We are going to do our part".

Propaganda was heavily used during war times to convince the citizens that the war effort was necessary and that they had to support it. Propaganda messages try to convince people to do or accept something. Most of the time propaganda messages appeal to Pathos, the emotional side of people that react to emotions rather that logic or reason. That is why an important aspect or propaganda is the using of famous or public figures to endorse the message, looking for people to accept it with no thinking at all.
