I bought the book from an old emploee for a friend for 50.00 , then he didn't want it , i sold it for 50.00 the one I have for my collection is signed , not for sale , but read this book , and learn about the Tarzan club of America , learn that Signal didn't go out of business they just moved to Houston and joined the areospase program ,
next time you change your oil and use a fram filter , look at the box , Signal , Standard oil has owned fram for years , you got to love this hobby .
