(I'm continuing some "reprints" of past comics-related posts from my politics blog as I plan on eventually deleting that category from the site ...)Who would have thought this, huh? Check out this advertisement from
Avengers #165 from 1977:

Yep, that's an ad for the
"All-New" X-Men. "All-new" because in order to
boost sales (yes, you read that right) in the mid-70s, writer
Len Wein and artist
Dave Cockrum revised the original line-up of
Stan Lee and
Jack Kirby's merry mutants that launched in 1963. Included in that line-up was a dude named ...
Wolverine. Heard of him? ;-)
But that's only part of the story. Check out what is circled in red from above:

Indeed --
X-Men magazine
used to come out once every two months!! Looking back from today this is an astonishing bit of trivia.
X-Men was actually almost canceled
completely because of poor sales in the early 70s. The book was only comprised of reprints of earlier issues for most of that time period. Then, in 1975, Wein and Cockrum came out with
Giant-Size X-Men #1 ...
... and about 20 years later the mutant characters were by far Marvel Comics' greatest creative asset. They pretty much remain so today, too. Wolverine may even be more popular than Marvel's "flagship" character of
Spider-Man. There have been three "X-Men" movies, and the "Wolverine" flick.
By the way, if you're looking for a nice copy of
Giant-Size X-Men #1, good luck. That, and make sure your bank account is well padded.
