In part: “I am sorry I cannot be at your celebration…But let me add the true way for the colored people of the Union to keep that anniversary is to resolve a pledge to themselves, each to the other, that they will never vote for any one who does not heartily & with all his might advocate & support a Civil Rights Bill on the model of the immortal Charles Sumner.” In very good condition, with scattered toning and soiling, some affecting first name of signature, tape to hinge, and a mounting remnant along inside edge of page.
