Book excerpt: The Penn State Football Button Book celebrates the coaching legacy of Joe Paterno and the glorious history of Nittany Lion football during the Paterno era. It does so, however, in a style unlike any other football book ever written -- through the use of the complete collection of "game day" booster buttons produced by Citizens Bank (and its predecessor bank sponsors) to commemorate each Penn State football game played over the past 32 years. The Penn State Football Button Book evokes exciting memories of the Paterno era using button images and unique and fun commentary rather than traditional game summaries. Book jacket.
