One other example of the 5c on Buff is recorded in Crown as part of the Manning collection (Phillips census), used on a cover to Edw. Hart, Auditor, Jackson Miss. The use of the provisional adhesive on this cover is something of an enigma. Government postage stamps were available at Montgomery as early as October 1861, and dated examples of the provisional handstamped envelopes show that they were phased out by January 1862. There is no obvious reason for Postmaster Welsh to accept adhesive provisionals in March 1862 -- in this instance, an old stamp may have been affixed and honored, and the 5c Green affixed at the post office to keep accounts reconciled.
