Erm... yes. Well, this is a little embarrassing. Remember when I said, back on Day Six, that I'd be doing a couple of these comparisons of frequently-homaged covers during the course of the blog's run? Well, I might have, y'know, completely forgotten. Still, I'm going back through the whole blog now, closing off any tangents that are still hanging around, and I think that over the next week and a day I'll have covered everything I said I was going to. And speaking of covers, back to the point.
In 1976, one of Marvel's lowest-selling titles was on the brink of cancellation. It was running reprint stories and was being published bimonthly. Rather than cancel it, Marvel decided to overhaul the line-up of the team whose book it was, and give it to new creators to re-stock the group with new characters and do something, anything, with it that would mean it avoided cancellation. The creators were Len Wein and the late Dave Cockrum, and the book was X-Men. When Giant-Size X-Men #1, featuring the debut of the new team (which featured characters like Storm, Nightcrawler and Colossus making their first appearances, and also had some short hairy grumpy Canadian guy in it), nobody could have guessed that they'd just witnessed the birth of what would become comics' biggest publishing juggernaut. They also couldn't have guessed that Marvel had just published a comic that had one of the most enduring cover images in comics history.
Now, in later years, X-Men-related comics have tended to return to this well quite a lot. It's a striking picture, and the thought of the old team reacting in shock to the new is a powerful image in that it implies violent upheaval of the status quo. Strangely, though, three of the most notable instances of it being homaged by other X-books feature non-violent things like babies and fat people.
