The autograph note to an unspecified recipient, but more than likely his eldest son Robert, is signed in the third person as Mr L and also as A Lincoln and dated and reads: Bravo! my good boy. Whether Mr L. shall be re-elected or not, he feels sure that you will stick to the cause of the country. A. Lincoln Nov. 2, 1864.

This note contains Lincoln’s second known use of the word Bravo. Three weeks earlier Lincoln had sent a cipher telegram to Indiana governor Oliver P Morton congratulating him on his re-election on October 11 concluding his telegram Bravo for Indiana and for yourself personally.

The note sold at a mid-estimate $45,000 (£36,290).
