*Marvel: They don’t come much hotter these days than Iron Man #55, wherein the cosmic arch-villain Thanos, nemesis of Marvel’s Cinematic Universe, made his first appearance, the brainchild of fan favourite writer/artist Jim Starlin. Thanos has of course gone on to plague Marvel’s heroes in comics and movies ever since, but here is where it all started. This landmark issue also features the debuts of Drax the Destroyer, Mentor, Eros (later Starfox of the Avengers) and Kronos. With Avengers: Endgame, in which Thanos is the Big Bad, breaking box-office records in cinemas worldwide, the character’s debut is only going to become more sought after. Our newest copy of Iron Man #55 is FN, cents with no pence pricing, one faint diagonal crease and minor corner and edge wear, but tight staples, good interior page quality and unmarred cover scene. On sale at £425.
