Written by ROY THOMAS, GARY FRIEDRICH, ARNOLD DRAKE & JERRY SIEGEL Penciled by JIM STERANKO, BARRY SMITH, DON HECK, JOHN BUSCEMA, WERNER ROTH & GEORGE TUSKA Cover by JIM STERANKO Buckle down your mortarboards, students of Marvel's merry mutants, 'cause we've got a summer crash course in X-Men classics coming your way! Lesson #1: It ain't easy being an X-Man. No sooner has their mentor, Professor X, died than who shows up but Magneto and the Brotherhood of Evil Mutants! Only a study in teamwork with Earth's Mightiest Heroes can help our grieving heroes make the grade! Lesson #2: Think twice before inviting family over. A friendly house call from the Juggernaut or Polaris, the daughter of Magneto himself, isn't the summertime bliss the brochure may have described! Lesson #3: Battling a bevy of baddies including Mesmero, Blastaar, the Red Raven, Warlock and Computo may cause cramps. Be sure to stretch before jumping into this pool! And for extra credit you can pull an all-nighter with the origins of Iceman and Beast, along with a rare solo story featuring the Angel! Consult guest instructors Jim Steranko, Barry Smith and John Buscema this July or risk failure at the end of the term. Dismissed! Collecting X-MEN (Vol. 1) #43-53, AVENGERS (Vol. 1) #53 and selections from KA-ZAR #2, 3 and MARVEL TALES #30.
