The Patent Leather Kid (1927)

"Fries of youth and courage that will set your heart ablaze! The love-romance that Broadway held dear to its heart for four months!"

The Patent Leather Kid is a 1927 silent film which tells the story of a boxer who scoffs at fighting outside the ring... particularly for the United States once it enters World War I. Eventually, he is drafted, is shipped overseas, and performs a heroic act, which results in his being severely wounded.
