The Opper Project, named after Ohioan Frederick Burr Opper, the first great American-born cartoonist, is an on-line collection of historic editorial cartoons. Covering more than one hundred years of American history, the cartoons are organized topically with associated lesson plans.
The cartoons are from the collection of The Ohio State University Cartoon Research Library. Most are American, but you will also find the views of some international cartoonists on the America of their day. There are some famous cartoons here, but most of the images are not the ones typically reproduced in text books and instructional materials.
All the cartoons are evocative and teachable, however. And to help you get started, they come with teacher-created lesson plans tied to the Ohio Academic Content Standards.
