A runaway slave broadside issued in Maryland in 1802 carries an estimate of $14,000-18,000 ahead of a sale at Early American History Auctions in Santa Fe, California.
The auction will take place on April 26.
The paper begins: "Forty Dollars Reward. Ranaway from the Subscribers, near Frederick-Town, on the 18th inst. the two negro men herein after described", followed by a description of the two men - who are named as "Negro Harry" and "Negro Len".
The lot is signed by slave masters Baker and James Johnson and is presented in exceptional condition, with light toning from its use by bounty hunters.
A cheque for $25 signed by Abraham Lincoln is another highlight, valued at $12,000-16,000.
It dates to June 13, 1859 and is made out to William Henry Herndon - a partner in Lincoln's law firm who later wrote the president's biography.
Herndon claims that he heavily influenced Lincoln's views on slavery and later wrote that the president was too slow to stamp out the practice.
Despite his close relationship with Lincoln, he was reportedly never invited to dinner as the president's wife detested him.
The lot features an exceptional example of Lincoln's autograph and remains in good condition despite its age.
