The world's largest cartoon museum opens this weekend at Ohio State University. The Billy Ireland Cartoon Library and Museum is home to millions of newspaper comic strips, books and cartoons dating to 1798.

Chillicothe native Billy Ireland was a well-known political cartoonist who made his mark on journalism in the U.S. in the early 20th century.

Ohio State officials have been collecting the cartoons since 1977, showing the spectrum of political, editorial and comedic works.
