What are examples of bias in revolutionary war propaganda?

How they put posters up that was more toward their preferences; it was in their favor and didn't really show factors of the other side

The most prominent example of biased propaganda during the revolutionary war was artwork of the Boston Massacre on the posters, which was showing the civilians as being peaceful when the soldiers started firing, which is not what happened at all. The civilians were harassing the soldiers with snowballs, and then one of the civilians threatened a soldier and the soldier shot him, igniting the violence.
