Because 1975 and 2025 share the same calendar dates, it is only fitting to reissue the original Mighty Marvel Calendar, first published fifty years ago and now a timeless classic from the Bronze Age of the Marvel Universe. Spiral-bound and printed on sturdy cardstock, the Mighty Marvel Calendar features Super Heroes and Super Villains, alike, with visual call-outs throughout the year for birthdays of noted Marvel staff and creators, key moments in Marvel history, famous quotes from fan-favorite issues, and other celebratory mentions. Each month is dedicated to a different Marvel character or group from Spider-Man and Daredevil to the Avengers and the Fantastic Four. As artistically designed and captivatingly written as any of the Marvel comic books, this calendar features original art created especially for it by iconic Marvel artists, including Jack Kirby, John Buscema, John Romita Sr, Gil Kane, Gene Colan, and others. Celebrated Marvel editor-in-chief and historian Roy Thomas wrote and edited it. Also included are major holidays and observances from around the world specific to 2025. No matter if it’s 1975 or 2025, always Make Mine Marvel!
