All-New All-Different: A Celebration of 'Giant-Size X-Men' #1
On this day in 1975, comics were changed forever. The book that changed everything? Giant-Size X-Men #1 by Len Wein and Dave Cockrum. The reason this book is so important? It's the first appearance of the X-Men. "But wait," you're saying, "the X-Men debuted in 1963's X-Men #1 by Stan Lee and Jack Kirby!" That is also true, but here's the thing about those X-Men: Nobody liked them very much, and there was nothing particularly special about them. Cyclops, Marvel Girl, Angel, Iceman, and Beast were students a prep school for mutants who fought goofy supervillains in between training sessions. They were a second-string Lee/Kirby creation at best.
