Cowboys & Aliens Circa 1952

Apparently, Steven Busti is claiming that "Cowboys & Aliens" was his idea back in 1994, published the following year in Bizarre Fantasy, and that Scott Rosenberg swiped it for Platinum's 2006 series Cowboys & Aliens. I haven't read either series or seen the recent movie to be able to compare them directly but, frankly, they both suspiciously sound a lot like Charlton's old Space Western Comics from 1952...

So, not exactly an entirely original concept we're dealing with here.
