I just loaded into the Ephemera Library the 32 page 1959 Speed Queen Facts of Superiority Book. It is just filled with beautiful images of Speed Queen washer parts and lots of great information about why Speed Queen was better. There is a great comparison of the Speed Queen design to both the Whirlpool/Kenmore and GE Filter-Flo designs. I highly recommended this one if nothing else just for the adorable graphics alone!
