A poster for Victor L. Berger, on display at the Wisconsin Historical Museum. Berger ran on the Socialist ticket.
Berger was a founder of the Socialist Party of America in 1901....Here's a closeup of the small poster at the corner of that display — replete with historical graffiti:
Berger ran for Congress and lost in 1904 before winning Wisconsin's 5th congressional district seat in 1910 as the first Socialist to serve in the United States Congress. In Congress, he focused on issues related to the District of Columbia and also more radical proposals, including eliminating the President's veto, abolishing the Senate, and the social takeover of major industries. Berger gained national publicity for his old-age pension bill, the first of its kind introduced into Congress.
