This is one of those curios when a forgeign license has a different market and publishing schedule.
Marvel is to publish a collection of the Ultimate Comics Spider-Man: Death Of Spider-Man in November.
But Panini/Marvel UK is to publish the same volume three months earlier, in August.
And they are also publishing something that Marvel US seems to have no desire to revisit, John Byrne's X-Men: The Hidden Years, the book set in the period while the X-Men comic was in reprints. Its cancellation led Byrne to quit Marvel for good. The run will be printed in a digest format, the first volume taking in the first seven issues, for £4.99.
UPDATE: John Byrne posts;
Just ordered a copy for myself.
