I recently purchased another index card autograph from an eBay seller. There are many Musial signatures floating around, and this one isn't as clean as I'd hope - the underline and player name doesn't add much for me, nor is the cut sig. mounted on an index card exactly what I'd call ideal - but it was a great price.
Stan "The Man" Musial was elected to the Baseball Hall of Fame in 1969, and passed away just a few years ago. This cardinal legend is one of the best players in my collection, though his autograph is far from rare.
This was a nice one to finally add, after a failed attempt in 2011 and another one in 2012.
