Here's the HINDU adv. from 1909 that 1st referred to the Southern Leaguer cards of which 2 were included in a HINDU pack.
It's only recently that we were able to ascertain that only 34 of the 48 Southern Lgrs. (SL) were printed with the HINDU back.
Subsequently, all 48 SL were printed with the OLD MILL backs. Then in 1910, all 48 SL were printed with the PIEDMONT backs.

Note that Breitenstein is pictured on both the HINDU and OLD MILL adv. But, his image in the HINDU adv. is reversed.
