CSA 1, 5¢ green (4 margins) used with known Selma target cancel on small lady’s cover to Miss Eudora Conley, Selma, Dallas County, Ala. endorsed “Kindness of Mr. Niall” at lower left. Likely, the stamp was already applied by the sender for posting to Selma but was carried as a favor to Selma by Mr. Niall who then dropped it at the post office for pickup. This was not uncommon. OVERPAID DROP use. $250.
