--Edited to add that I forgot to check the archives! Rookie mistake... Kawika came to the same conclusion as me back in February of 2010 in the thread he mentions below.
Great Find!
I attach your photo with a little headshot of Charles Armbruster. Looks to me like the guy in the bottom left of the photo.
If you think it is him, he only played for Portland in 1909 and 1910. Played for Red Sox and White Sox in pro career and I think he has a T206 as well as an Obak card.
What do you think?
