REA to auction T206 Wagner in April

[brass_rat]

Hi everybody,

First, I would like to take the opportunity to say hello -- this is my first post here -- I've been reading the board for a few months, and it's nice to finally write.
I thought it would be interesting to note that REA posted on their blog yesterday that they will be auctioning a T206 Wagner (PSA 1) this April.

I find it somewhat amusing that they've decided to name it (The Connecticut Wagner)...but the story is at least interesting. (One point to note is that the consignors do not remember the name of the gentlemen that sold them the set. Maybe I'm just a little detail crazy, but I keep records of every card I buy, including the person I bought it from...)

Question -- why would the PSA Cert Verification say "T206 unknown back" when the back is clearly identifiable?

Good to be here,
