Confederacy, Confederate States of America/General Post Office Department/Auditor's Office. Official imprint on blue cover to Fayetteville, postmarked "Richmond, Va./Apr. 1863" cds with Auditor's manuscript free frank of "B. Baker", Very Fine and choice, a rare unlisted imprint (Pictured in Monroe Book, pg. 32). Estimate  $300 - 400. The Confederate States of America Postage Act of March 15, 1861, abolished the postage free franking privilege, but did make special provision that the Postmaster General and various other Post Office Department officials could send official mail free of postage when endorsed on printed envelopes prepared for this purpose. These Official envelopes are far rarer than the Semi-Official imprint envelopes, which did not have free franking privileges. $0 (Image)
