A War Worker Calls for a Favor, late 1862. Peter Waddell, The Visit, oil on canvas, 36 x 48.

Mary Livermore, a prominent abolitionist and women's rights activist, championed many causes including the U.S. Sanitary Commission that ran hospitals and collected supplies for soldiers during the Civil War. Livermore met with President Abraham Lincoln after he announced he would sign the Emancipation Proclamation. Lincoln later donated the original signed copy to raise money for the Commission. The Proclamation sold at auction for $3,000.
