This is a very important item. While it is not a particularly rare book, it has three separate identifying plates reading 'Hauptarchiv der NSDAP Nr. 2,66' which basically states the book is from the Head/Main Archives of the Nazi party.

No matter what anyone thought of Frank Rizzo, nobody was of little opinion and his years as mayor of Philadelphia were extremely interesting. Rizzo, who graduated step by step from beat cop to mayor, was known for his toughness and one famous photograph showed on his way from a full dress function to a prison riot with a billy club tucked into his tuxedo. This book is a guaranteed good read. Priced half of cover price.
