About this source
What it is
This is a political cartoon by Joseph Keppler, published in Puck magazine in January 1889. It shows the Senate chamber dominated by huge caricatured figures representing industrial trusts, including Standard Oil.
Why it matters
The cartoon captured public anger at the growing power of trusts and monopolies during the Gilded Age, and at lobbying's influence over lawmakers. It became one of the most reproduced images of the era and is seen as contributing to the push for antitrust laws like the Sherman Act. As head of Standard Oil, Rockefeller was one of the industrialists this kind of criticism targeted.

- What does the sign reading about a 'Senate of the Monopolists' suggest about the cartoonist's opinion?
- What is left out of a cartoon like this that a written account might include?
