While I respect Scot Reader's voluminous writings on T206 there is clearly not a consensus on the Cobb back as being included or not, in T206. That being said there would be no "T206" without the person that invented it, Jefferson Burdick. If anything, when there is not a clear consensus on an issue, we should go back to what Burdick wrote since he is the one that imagined it. There is no debate that he came up with the ACC system of classifying cards in the US. And I realize that even Jefferson said his ACC was, and always will be, a work in progress. He stated the Cobb back was a T206.
