Here's the cover to issue 15 (September 1978) of the Marvel comics Star Wars series, which is another one I remember very fondly:
The cover depicts Han Solo engaged in a blaster duel with the space pirate Crimson Jack and his men, just outside Jack's flagship, a captured Imperial star destroyer (which, interestingly, was never given a name -- can you imagine something like that nowadays?). It doesn't take a rocket scientist to notice something weird about this illustration: neither Han nor Jack are wearing spacesuits, even though they're clearly floating in the void. What's going on here?
As a show of trust, when Han agrees to meet Jack in space to make an exchange of items each of them wants from the other, he does so without wearing a spacesuit, because such a suit could easily conceal all sorts of weaponry. Fortunately, Jack's star destroyer can "extend its magnetic field" in order to hold the vacuum of space at bay. There's still no gravity and no oxygen, of course, but at least Han can float around wearing just a SCUBA tank without dying.
This is pretty much the Marvel era of Star Wars in a nutshell: if it looks and feels right, everything else be damned. And since there was so little nailed down about the nature of the Star Wars universe, Marvel had a lot of license to do stuff like this. Sometimes it worked, sometime it didn't, but, looking back on it, what most impresses me about it is how fresh it still feels. There's nothing tired about these Marvel comics and perhaps that's more a function of when they were written rather than any inherent goodness. Still, I can't deny that, coming back to them now, they feel like a much needed breath of fresh air.
