Political Cartoons

In class today, we analyzed a few political cartoon that circulated in the colonial times. Many of these cartoons were used to spark unity amoung the colonist against the British. I want to get some opinions on why Paul Revere only portrayed white men in the cartoon. Where was Crispus Attackus? Who was he? What is his significance to this event? Why do you think that Paul Revere left him out of this cartoon?
