License cartoons from CartoonStock, there are gobs of em on there

”Brainwaves” ran in syndication in papers and online and to this day, these panels roam the Earth in books, magazines, presentations, a Smithsonian Astrophysics Observatory exhibit on black holes, psychology textbooks, and refrigerator doors. One of them is even taped to Paul Giamatti’s character’s office wall in the movie, San Andreas. Fame!
