 Seems like the entire 1K batch from the original collection is 150-only and 150/350 subjects, which if true not only points to a single source but 1909 acquisition (I am assuming that all of the 150/350 cards in the 1K batch have 150 backs like the Green Cobbs). Interesting that the SLers are Old Mill; that hints at introduction of the Old Mill Southern back in 1909 which is earlier than I thought.
