Of course, Buckler was virtually omnipresent on Marvel's 1970s covers, competing with Gil Kane and Kirby for ubiquity. As the 70s gave way to the 80s, Buckler landed at DC where he again turned in stellar work. While Rich Buckler will most likely never be mentioned among the masters, he must be considered one of the Bronze Age greats, for sheer output alone. And if you dig deep, you may be surprised at just how much he put his hands on - corner boxes, covers on mags you'd least expect (the All-New, All-Different X-Men, for example), and big projects like DC's Limited Collectors' Edition treasuries.
