Harry Blackstone,” adding a nice profile portrait sketch to the right of his signature. Blackstone was in Kentucky and as a VIP visitor was probably appointed honorary Kentucky Colonel by the governor’s office. Also signed in ballpoint by The Great Jarvis. Rolled and in very good condition, with mild toning, scattered creasing, dings, and small tears to edges, and some light wrinkling. R&R COA.
