I liked the prologue to Star Wars From the Adventures of Luke Skywalker. How it described the Emperor how he was President and destroyed the Jedi and subverted democracy. It was not at all how the Emperor was portrayed later in Empire or Jedi. He was a politician controlled by the very boot lickers who elevated him to high office.
I love the back cover of the 1976 edition. Luke Skywalker Challenged the Stormtroopers of a Distant Galaxy on a Daring Mission- Where a Force of Life Became the Power of Death! The McQuarrie cover almost promises a Flash Gordon/Edgar Rice Burroughs style pulp adventure.
