Gilbert MainesAt the time of the t206 cards being issued, all major league cities were subject to cold weather (Wash. was southernmost). A quick look at the alphabetically first two dozen t206 players reveals a nominal equal distribution of upturned and downturned collars.
As you suggest though, this "mystery" may be easily explained.
I wonder which cards could be checked for maybe the Southern League Teams. I bet they rarely travelled out of the warmer climate for games.
