Looks real to be, based on this site:

The only issue i have is the U, in U.S.A , Does the U, look chopped off at the top??
The other characteristics look right/
The red box is not too wide, the stitches on the ball point right, The S in Dimmagio is lined under the right letter.
I would like to see a better front scan of the 'stars' on the front to see color pixels clearer.
