I recently acquired this McBride AB 350 below and noticed the light blue mark above the back pocket... I was unable to search and find another similar mark on any McBride cards until I located this one (see below) from a Goodwin Auction that ended on 9/26/14. It is a Broad Leaf 350 with the exact Blue Mark on it! I'm wondering if anyone else has ever come across one? Any thoughts on the printing of these two cards? There is obviously some connection here. All T206 expert opinions welcomed!
