I was poking around the LA84Foundation.org site last evening looking for some info on the Tri-Copper League of Arizona. I stumbled across this advertisement for what we now know as the W600 series of cards.
|Sporting Life - November 23, 1907|
Interesting to note that in the above ad, Ty Cobb is listed as Tyrus W. Cobb. His middle name was Raymond.
