This single-panel comic shows Abraham Lincoln pulling down the pants of another man while shouting "Take that, Salmon P. Chase!" The caption below reads "Abraham Lincoln: Great Emancipator. Great Epantsipator."

The joke is a simple pun on Lincoln's famous title, "The Great Emancipator," given to him for freeing enslaved people through the Emancipation Proclamation. The comic invents the word "Epantsipator" -- a portmanteau of "emancipator" and "pants" -- to describe someone who removes other people's pants. Salmon P. Chase was Lincoln's Secretary of the Treasury and a political rival who also sought the Republican presidential nomination. The humor is entirely in the absurd wordplay and the image of a dignified historical figure engaged in juvenile behavior.
