The Australian Outback Era X-Men by Marc Silvestri and Dan Green
From Comics Scene Vol. 2 #1 (My scan)
I have never seen this artwork anywhere. Never in a reprint, never even online anywhere. As far as I know this is exclusive to just this magazine. It is such an amazing piece. My favorite X-Men team by my favorite X-Men art team rather blatantly depicting them as the Wild West Outlaw team Chris Claremont envisioned them as when they went Down Under.
