Untold Tales of Spider-Man #21

Spider-Man charges front and center on Pat Olliffe's energetic cover, with the original X-Men — Angel soaring overhead with wings spread wide, Iceman in his icy form, Cyclops, Marvel Girl, and Beast — surging forward behind him in their classic yellow-and-black uniforms. The bold "Enter: The X-Men" banner sets the tone for what looks to be a thrilling team-up, all captured in Kurt Busiek's celebrated retro-era series that fills in the early chapters of Peter Parker's career. At just 99 cents, issue #21 of Untold Tales of Spider-Man delivers a fun, silver-age-flavored charge that's hard to pass up.
