*Marvel: ‘A Special Once-In-A-Lifetime Issue’, the cover of this one-shot boasted, and its unique position is simply a result of a scheduling tangle which arose when Marvel was finally allowed by its distributors to increase its range of titles. The Hulk took over the numbering of Tales to Astonish, and Captain America the numbering of Tales of Suspense, but that left ‘orphaned’ chapters of the Iron Man and Sub-Mariner serials languishing, so they were used in this oddball one-off so that both Iron Man and the Sub-Mariner could start off their #1’s with clear storylines.  This UK price-stamped copy is in a superb grade (VF+ £100), with only the very faintest corner wear preventing a higher grade. The white-background cover is clean and unmarked, and the cover and gloss vivid and fresh. One of the easiest Silver Age Marvel titles to complete – buy one and you’ve bought them all!
