Chicago artist Leonard Volk produced... the casts of Lincoln’s hands on May 20, two days after the Republican Party nominated him for the presidency. Lincoln’s right hand was still swollen from shaking hands with supporters. To steady his hand in the mold, Lincoln went out to the woodshed and cut off a piece of broom handle. Volk later placed the piece of handle in the cast displayed here.Further information at the Smithsonian's National Museum of American History.
