What a beautiful Matthews card you picked up. Congrats on a tough card.
I have been kind of on the sidelines as of late churning through my collection with a slight change of focus toward high end Post War HOF RC's. Although not a rookie card, the deal on this was to good for me to pass, up on a card I have wanted for quite a long time. Can't say that I am a very big Mantle collector, but really enjoy having this card in my collection.
