Published in 1943, this book is a collection of cartoons that appeared in mass media publication such as newspapers and magazines. While some of the cartoons feature people in the public eye at the time and so are somewhat dated, most of them are about human situations and so are relatively timeless. They do reflect the social customs of the times, although there were many changes during the first half of the twentieth century.
Several of the cartoons reflect the social stratification of the times, specifically during the Depression years. The cartoons are American, so there is little material dealing with what was happening in other countries. Almost nothing about the aftermath of World War I in Europe and how the entire continent struggled to cope with so much loss of blood and treasure.
If you are a fan of cartoons that deal with social, political and economic issues, then these cartoons are timeless.
