NEW YORK TRIBUNE, September 3, 1863  The front page  has a one column head: "President Lincoln's Letter" with subheads "A Plain Statement of His Position" "He Maintains the Emancipation Policy" "How a Compromise Can be Effected" "The Employment of Negro Soldiers". This has the entire text of Lincoln's reply to an invitation to a meeting of "unconditional Union men" to be held at Springfield, Illinois. The letter, datelined "Executive Mansion, Washington, Aug. 16, 1863", is addressed to the "Hon. James C. Conkling". Although he politely declined the invitation, Lincoln used this opportunity to respond to those critical of his war policy, and the Emancipation Proclamation. In the letter (which he designed as a speech to be read at the rally), Lincoln states in part: "There are those who are dissatisfied with me. To such I would say, you desire peace, and you blame me that we do not have it. But how can we attain it? There are but three conceivable ways..." and more. Much more about the war as well as the Emancipation Proclamation, the letter is signed in type: A. Lincoln. 
The issue is complete in 8 pages, and is in very nice condition.
