This document discusses several political cartoons by Thomas Nast criticizing Boss Tweed and Tammany Hall. The cartoons use symbols to portray Tammany Hall as corruptly controlling the government like a machine for their own benefit. One cartoon shows police ignoring criminal activity, suggesting Tammany Hall protects criminals. Another links Tammany Hall figures together in a boxing match, with the pointing finger ending on Boss Tweed, indicating he is responsible. The conclusion is that through these cartoons, Thomas Nast clearly held a negative opinion of Boss Tweed and Tammany Hall as corrupt political machines.
