Hard to beat Jamie Keenan‘s cover for This Way for the Gas, Ladies and Gentlemen.
From my essay:
“Several nearly monochromatic covers reveal unexpected eloquence by using obscured, distorted and disappearing text to great effect. Jamie Keenan’s truncated words that appear to be in the process of sinking into a heavily textured background suggest the methodical erasure of countless lives that vanished into nothingness.”
