A few years ago (close to a decade even?) DC started printing certain perennial comics in oversized, hardcover editions. The umbrella term for the format was "Absolute". These are HUGE, slick collections with bonus material and although cumbersome, very handsome and impressive.
This treatment is reserved for highly acclaimed comics (Dark Knight Returns, Watchmen, Authority, New Frontier...) but I'm such a Suicide Squad geek that I think the title deserves that format. Unfortunately, the series didn't even rate a "Showcase" treatment (in black and white newsprint) despite a solicitation and release date in previews. I guess SS lives on within us "in the know".
