From August 1983: the final four (16-19) of MARVEL UK's ill-fated first colour weekly*: THE MIGHTY THOR. Undone by dated strips and (initially) dire print quality.
As the announcement made clear, Thor was swiftly folded in with THE X-MEN, Marvel's other experimental new weekly (also hindered by the same problems). Although, technically, the X-Men merged with Thor (the numbering carried on where Thor left off), it was treated as a merger of equals with both strips retaining equally billing on the masthead (and space inside) for the nineteen week run (prior to the merger with SPIDER-MAN AND HIS AMAZING FRIENDS). They even alternated covers.
It's taken me almost a year to complete this cover gallery. When I had to break away (because of work commitments) from the Blog for a while, this was one of the ongoing topics left hanging. And I forgot all about it when regular posting resumed. So here - finally - are the last few covers.
*CAPTAIN BRITAIN can technically stake that claim... but the centre section (housing the Fantastic Four) was in black & white.
