Congrats John. As of this moment (and I reserve the right to change my mind) I don't think the Ty Cobb back is part of T206. Even though I have been a staunch supporter of Burdick's writings, the more I study him, the more I know HE KNEW there were mistakes and wanted help correcting them. I think I could go with a type 1 set of backs that has all that were inserted into packs/containers and then a type 2 back set including the anomalies. The Type 2 being the master set but not necessary to consider the subset complete. As I said, I could change my mind but those are my current thoughts. Great looking backs you have there!!
