I won this lot of 4 T207 cards with the brown-ink printing on the back in the recent REA auction:

Interestingly, SGC has noted "Brown Back" on the flips on only 2 of these 4 cards. I plan to ask SGC at the upcoming Philly Show to re-holder the other 2 with this notation. The only card I'm keeping for my collection is the WaJo card - the other 3 cards are available FS/FT.
