Short answers, pulled from the story.
Pizzazz was a youth-culture magazine published by Marvel Comics from 1977 to 1979, running for a total of 16 issues. It covered popular movies, rock stars, and celebrity culture alongside comic strips and puzzles.
Shaun Cassidy appeared on six covers, more than any other figure. The Hulk appeared on five covers, Spider-Man on four, and Peter Frampton on three.
The 1977 Star Wars installments in Pizzazz are the first original Star Wars stories not directly adapted from the films to appear in print. They preceded both the original stories in Marvel's Star Wars comic series and the 1978 novel Splinter of the Mind's Eye.
The first arc, "The Keeper's World", was by Roy Thomas, Howard Chaykin, and Tony DeZuniga. The second arc, "The Kingdom of Ice", was by Archie Goodwin, Walt Simonson, Klaus Janson, Dave Cockrum, and John Tartaglione.
Pizzazz was canceled after its 16th issue, before the final two chapters of "The Kingdom of Ice" could be published. Those chapters were later printed by Marvel UK in their Star Wars Weekly comic, appearing in issue 60 in April 1979.
Regular features included a comic about Amy Carter's life as the President's daughter, a serialized Star Wars comic, and one-page "Hey Look!" comics by Harvey Kurtzman originally drawn for Timely Comics in the 1940s. Columns included the dream-analyzing "Dream Dimensions" and the advice column "Dear Wendy".
