I doubt its pencil, it looks like a faded black pen. anyway, the Billy Martin is good, as is the Berra, and Catfish, and Elston Howard. I believe there is also a Bob Lemon on there. The Munson, unfortunately, is clubhouse.
Thanks terrier, I didn't like the Munson at all, and you verified my thoughts exactly. That being said, I will take your word on this matter before I would ever trust my own.
IMO, Terrier is spot on with the Munson. The entire formation is off and it's in an anachronistic style, more indicative of an earlier style.
