Try number two. Lincoln's missing First Inaugural Address. At Harrisburg he'd entrusted a satchel containing the address to son Robert. Robert couldn't remember what he'd done with the satchel. Lincoln told Lamon, "I'm afraid I've lost my certificate of moral character, written by myself." https://books.google.com/books?id=mGMDAA...er&f=false
