Professor Xavier and the X-Men #18

The cover by Max Kirby sends off this series in style, presenting the original five X-Men — Marvel Girl, Cyclops, Angel, Beast, and Iceman — in their classic yellow-and-black uniforms, with Angel soaring above the group and Iceman crackling with icy energy below. Billed as a "Special Goodbye Salute to Our Heroes," issue #18 closes out Professor Xavier and the X-Men on a fond, nostalgic note, celebrating these "Legends of Yesteryear" while holding onto "Hope for Tomorrow." At just 99 cents, it's a warmly sentimental capstone to this retro-flavored series revisiting the team's early days.
