In the T206 set there is a subset of 48 cards of players commonly known as Southern Leaguers. The cards were issued with three different backs; Piedmont 350; Old Mill; and Hindu. Of the three, Hindu backed cards are the rarest and most sought out by collectors.
A while ago I was fortunate to win a lot of 16 Southern League cards in a major auction. Over the course of the next few months I sold off most to other collectors. Shown here is that lot of Hindu backed T206 Southern League cards.
