Rare T205 and T207 backs?

[tbob]

Andrew- yes, Factory No. 3 is correct.
Patrick- I would beg to differ with you on the Cycles not being tough. I think you have to factor in that all non-Recruit back cards are tough in general and then examine which of the Broadleaf/Anonymous/Cycle backs are tougher for each card. I partly agree with you that Cycles are not the toughest of the 3 (I think Anonymous backs are the toughest) but after I completed my set I began to go after a subset of all red Cycle backs for the tough cards and believe me there are several which just don't seem to appear ever with the Cycle backs. I don't know if this is because collectors prefer that bright red Cycle back and hold on to them for their collections as opposed to the drab Anonymous backs or "in-the-middle" Broadleafs...
Chris- yes, there are non-completed sheets of T206s besides advertsing sheets.

And of course the almost impossible Red Cross backed T207s meet all qualifications of being "rare."

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?
