Good info, Todd. Here is more evidence that the print run for the 1916 cards was early in the year, prior to the start of the season. Reulbach is shown with Pittsburgh. From this sabr bio..."The Pittsburgh Pirates acquired the rights to the big right-hander (Reulbach) in the Federal League dispersal draft, but sold him to the Boston Braves just before the start of the 1916 season." So, the card must have been printed between the date of the draft and the start of the season.
