Uncanny X-MenUncanny X-Men.

Uncanny X-Men, originally published as The X-Men, is an American comic book series published by Marvel Comics since 1963, and is the longest-running series in the X-Men comics franchise. It features a team of superheroes called the X-Men, a group of mutants with superhuman abilities led and taught by Professor X. The title was created by Stan Lee and Jack Kirby, met with a lukewarm reception, and eventually became a reprints-only book in 1970. Interest was rekindled with 1975's Giant-Size X-Men #1 and the debut of a new, international team.
