Looking for some resources on cartoons to use in your classroom? The Library of Congress has this wonderful section packed full of more than " 500 prints made in America during the eighteenth and nineteenth centuries encompasses several forms of political art. Most of the prints are from the division's PC/US series, which consists of individually cataloged political cartoons and caricatures."
You can also use the search functionality provided by Library of Congress to refine your searches and browse through the titles provided there. I invite you to have a look and share with us what you think of this resource.
I have learned about this resource from a post by Richard Byrne.
