Ted ZanidakisA more complete answer to your question.....The printing of Joe Doyle cards went through 3 phases.....
1st....Piedmont 350 run with "Nat'l"....this error was caught very quickly (less than a dozen in circulation).
2nd....Hastily, Amer. Litho. Co. (ALC) erased "Nat'l" from their plate, leaving a remnant of the "N"......then
printed Joe Doyle with Piedmont, Sweet Caporal (Fac. 30), Polar Bear, and Old Mill cards with this Mark.
3rd....ALC erased this Mark, printed Joe Doyle with EPDG, Old Mill, Piedmont, Polar Bear, Sovereign, Sweet
Caporal and Tolstoi backs.
Here's a my data on the Joe Doyle "printer's Mark" as a function of T-brands (142 samples)......
T-brand.............Mark....No-Mark
Piedmont 350........7.........41
Sweet Cap 350......4.........55
Polar Bear.............2.........22
EPDG....................0..........1
Old Mill..................1..........5
Sovereign 350........0..........2
Tolstoi..................0..........2
