The T215-1, and its British counterpart with the PIRATE backs, comprise of the same 96 card fronts.
Both these sets are white-bordered with Brown captions. Approx. half of the fronts were derived from
the 350 series of the T206 set, and the other fronts were derived from the 460 series. Therefore, my
guess is that the T215 set was printed and issued in 2 series....1st in 1910 and the 2nd series in 1912.
