Bandwagon:
This poster was used during WWII . It was suppose to convince people to not ride alone and to conserve gas. They were saying that everyone was doing it because they didn't want to be "riding with Hitler" or supporting Germany. So, in a way, joining a car-sharing club would show that they didn't support Germany at all.

Testimonial:
In this ad, Shaq tells how he always uses Icy Hot after long, hard games. He guarantees that if it works for him then it will work for anyone. Shaq is a very known person so that is why they use him as their spokesperson. The company believes that most people will believe him.

Emotional:
There are many ads about animals that need to be saved, like this poster. This particular ad doesn't want you to get animals from anywhere except a shelter. On their website they tell about how you should never buy a puppy at a pet store or on the internet. They believe that puppy mills aren't right (which they aren't). This ad is emotional because they make you feel sad about puppies and it makes you want to adopt one.
