Aaron M.Al, love the Cubs pin and absolutely LOVE the Maris "60 in 61" pin! (email at aaron1050@aol.com if you are interested in selling either! 
)You've inspired me to take some photos and add to this thread. Pinbacks are my favorite niche within my vintage baseball memorabilia collection.
But before I do, does anyone have this 1912 Boston Red Sox World Series pin? I have been looking for a decent example for ages and will pay a mighty premium!
