CSA 11-AD, 10¢ blue (faulty) tied by badly worn Army field cancel that has become little more than a smear. Addressed to “Mrs. Rebeca Peterson, Chappells P.O., G.&C.R.R., South Carolina, in care of Peterson Mail.” Opening tears across top and upper right around stamp. PETERSON’S PACKAGE OR PETERSON’S MAIL is a known but, as far as I am aware, an unresearched regional mail service. A perfect postal history project for someone with curiosity and tenacity. Ex Wayman. $150.
