I'm surprised this thread has received so few responses the pdf file Tom
posted of the ATC journal is incredible information on a large number of
sports and non sports tobacco cards.
The first two index pages list the different brands and most of the pages that they are
on in the journal.
A couple of interesting things I see about t206's that haven't been mentioned
is that 13 of the 15 t206 brands (not including Ty Cobb) are on the index page
but EPDG and Polar Bear are missing also a few of the T206 brands say began
packing for all states except Ohio on some of the ledger pages.

I think the most interesting thing I found is on the first Carolina Brights page
in the ledger.
John posted one of the Carolina Brights pages in the above post but unfortunately the packing and shipping info has been ripped off but on the earlier Carolina Brights page on the side it says "began packing ball pictures Piedmont back backs in Carolina Brights 12/8/09 or 12/18/09"(I cant tell which). And after that it says began packing 2 ball pictures with C.B. backs but it doesn't have a date.

To me it seems to indicate that before they began printing the Carolina Brights backs on t206's they were inserting Piedmonts in the C.B. packs.
