"The Contentnea Series One backs identify the cards as being from the ""First Series."" Unlike most other card issues of the period, they were not printed with the factory number of the cigarettes packed with the cards, as required by law. This apparent oversight was subsequently corrected by the use of a hand-stamped ""Factory No. 12, 4th Dist. N.C."" Such hand-stamped overprints have been found in black (very light impression) and purple. There are unconfirmed reports of green-stamped backs."
