While I agree with the veteran board members that if you're going to use the ACC designations that the Cobb back is a T206 because Burdick said so, I also think it should be acceptable to talk about why he may have classified cards the way he did and why we may classify them differently with what we know today.
Chris to answer your question if I were to classify the white border cards in a similar method to Burdick I would not include the Cobb back in a group with the other cards we call T206's. My opinion could be changed easily as I don't profess to have all the facts.
Though this subject has been discussed over and over I am curious what those that care think of the following.
American Tobacco had controlling interest in F.R. Penn at the time that the Cobb brand tobacco was produced. However the Penn family still had operational control of the company. Isn't it possible that Penn had ALC produce these cards for their tobacco with the blessing of ATC? If this were the case wouldn't it be an F.R. Penn issuse and not an ATC issue? Couldn't this also explain minor differences such as gloss?
Sorry Jim VB, some of us are just nerds for these kinds of details.
