I just saw your post Brendan, I agree with you that the coolest thing in there (of the MANY really cool items) is the (very condescending) letter from the team's owner (a guy named Branch Rickey) telling Clemente that he is not worth the $10,000 per year he wants (in response to a $7,000 offer).
Both the original letter from Roberto and the response from Mr. Rickey are quite amazing.

The owner of the museum is a collector / packrat, like many of us, and is quite close to the family. All three sons and Vera Clemente were involved, and present, for the tour I was a part of.
