This book promises to be spectacular with its cover—a 3-D lenticular rendering of the great left-hander, from windup to follow-through—and largely delivers. Carrilho uses graphite on paper, with lavish use of burnished gold accents, Dodger blue and a calligraphic red line, to craft breathtakingly dramatic and dynamic pictures. Winter adopts the voice of an old-time Dodgers fan, complete with dropped gs and a liberal helping of ain’ts, to tell Koufax’s story: how he was wild at the start, how he had six magnificent years, how he kept to himself, would not play on a Jewish holy day and retired at the peak of his powers before he lost use of his arm entirely. The cadences of the narration are particularly effective in showing the cost of greatness in physical pain and effort. Box-score–type inserts provide relevant stats and anecdotes, and the whole manages to be vibrant without being cluttered. Great baseball stuff, and a visual treat for young fans and their parents and grandparents. (Picture book/biography. 5-9)
