As the country grows increasingly diverse and complicated, Americans seek, and occasionally find, a common thread to unite them. And, as Jim Lilliefors reveals in his new book, that common thread is what the baseball cap is made of indeed, what has transformed it into Americas National Hat. As fads go, its no longer even a fad, but a part of the national identity that, for better or worse, is a symbol of America. It feeds an illusion that Americans cherish that despite their differences, and no matter what position they play when wearing a baseball cap, theyre all part of the same team. Exploring every aspect of caps and their culture including the history, manufacturing, and evolution of baseball caps; collecting and caring for caps; cap etiquette; and even cap urban legends and packed with photos throughout, Ball Cap Nation is a delightful look at a uniquely American phenomenon.
