"Lucky 7" find - Cobb with Cobb back

[Steve D]

I received the latest SMR a few days ago, and was just reading the story on the Lucky 7 find, when I noticed something about the cards. It appears there is a difference between the cards.

Specifically, four of the cards (cert #s 25470302, 25470303, 25470306, 25470307) have the normal black border around the portrait and red background. The other three cards (cert #s 25470301, 25470304, 25470305) do not have the black border. Additionally, on the four cards with the border, the olde-english D on Cobb's uniform is black, while it is gray on the three cards without the border. Interestingly, there does not seem to be any difference in the black shade of Cobb's collar; it is black on all the cards.

I wonder about the previously known Cobb/Cobb cards, and how they match up.
