I send you with this a proof of my engraved portrait of President Lincoln, Upon which I have been engaged so long, engraved as you are aware after my own painting. As a work of art, I submit it to yourselves and to the public on its merits. That it is a truthful portrait or Mr. Lincoln, as he appeared in his calm and thoughtful moments, I have the assurance of many who were Ultimately connected with him during hid whole official career, as well as the testimony of others who enjoyed his acquaintance for many years. On this point I would ask your attention to the opinions of Mr. Sumner, Mr. Stanton, Mr. Trumbull, and Mr. Colfajx, contained in the letters which I enclose.
The execution of this portrait has been a pleasant labor to me during the many months I have been engaged upon it; and in executing it, 1 have endeavored not merely to gratify a professional ambition in producing a work of art, but 1 have sought, so far as could be done in one picture, to represent Mr. Lincoln as he was, and as he will be known in the pages of history and biography.”
