I Will Work Harder
This is good propaganda because all the animals on the farm respect and listen to Boxer. The animals really respect Boxer, he is very liked and does lots of work for the farm, this shows when he gets hurt from doing so much work. When he got sent to the knackers, the animals weren't the same after he was gone, they tried as hard as they could to save him, because they didn't want to be without him. This is an example of testimonial propaganda, all the animals on the farm know Boxer well, and they all really respect him.
