Rare T205 and T207 backs?

[hank_jp]

While the T207 Red Cross back is undeniably the toughest of the backs in that series [about a dozen are accounted for], the blank back cards are also hard to come by. I have seen even fewer of the "Brown Ink" backs, than blank backs and I believe they are very underrated ... they just do not get the attention of T206 brown backs, perhaps because they have been limited thusfar to the common Recruit brand.

I have had quite a few blank backs over the years and I have found that the T205's are the toughest to find, followed by the T207's and then the T206's, which also has proof cards with blank backs.

I wonder if anyone has seen proof marks on the front of any T cards other than T206 and T3 or had any T 205's or T207's labeled as "Proof" by the grading services?
