kind of a minor point wrt SGA 4x09
No meta, but I know I'm not the only one whom it has been driving nuts trying to figure out what Sheppard is reading in this episode, and I finally managed.

It drove me crazy trying to figure out what comic Sheppard is reading, but the file I initially downloaded wasn't high-res enough, and I could just recognize an older (i.e. pre mid-2005) DC logo and the general layout. Then after I wasted almost three hours (!) on a brute force method last night, going through a DC cover database month by month from 2005 backwards until I got to the late 1990s but still had no success, I gave up on that with he suspicion tht this might not be a real comic, and downloaded a larger version of the episode.

And indeed I don't think this is an actual DC comic. However you can read the text, and apparently Sheppard is a fan of a comic called "Cosmic Capers", that on his cover has both a DC logo and something that looks a bit like the Spidey logo Marvel put on its comics for a while, but it could be something else, also I think I can read "Marvelous Comics Inc. -- Comix Presents -- Cosmic Capers" on the cover, but you can judge for yourself. I also made two screencaps where you can see part of the interior pages.
