VERY FINE. THE ONLY RECORDED EXAMPLE OF ANY CONFEDERATE POSTMASTER'S PROVISIONAL ON AN ADAMS EXPRESS COVER FROM BOSTON.
Very few covers are recorded with Confederate provisional stamps or markings used in conjunction with thru-the-lines express service. This group includes the provisionals of Atlanta (handstamp), Houston (handstamp), Lynchburg (press-printed entire), Memphis (adhesive), Mobile (adhesive), Montgomery (handstamp), Nashville (adhesive and handstamp) and New Orleans (adhesive). To the best of our knowledge, this is the only Memphis thru-the-lines express usage, and it is the only provisional/express usage from the Adams Boston office (whose markings are rare in their own right).
