what book did maniac give grayson

From the text:

Maniac gave Grayson a pair of gloves and a woolen cap and a book. The book did not appear to be as sturdy as the others lying around. The cover was blue construction paper, and the spine, instead of being bound, was stapled. The text was hand- lettered, and the pictures were stick figures. The title was "The Man Who Struck Out Willie Mays."
