File this in my "going down a rabbit hole & then finding someone actually has one for sale" collection. Not a ton of information out there, but this fanzine appears to be the first published work, or earliest published work that still exists, by Walt Simonson. A little information here: https://gobacktothepast.com/fabulous-find-abraxas-1-fanzine/ & Walt tweeted about this before, but I think misidentified it as a copy of "The Outsiders", a URI fanzine for which I can find no copies, scans or sells (the ebay link from >4 years ago is dead). I presume the Outsiders thing exists somewhere b/c it's listed in the GCD. Walt is visiting a con close to me this summer....
Cover is a heavier cardstock. Paper is a bit thick. This inside of the back cover (Batman) has a "400" in red that might be an indicator of which copy of a smaller print run this is, IDK. Remarkably clean & white for a fanzine that's >50 years old. Cover is not described, but looks like Mephisto
