I've written a few words about Mike Mignola and Paul Buckley's Heart of Darkness cover for Grafik. I'm a little bit obsessed with the blackness of Mignola's black – it's just so very  … black. Perfectly suited for Conrad's story, which incidentally starts where I was born:

The sea-reach of the Thames stretched before us like the beginning of an interminable waterway. In the offing the sea and the sky were welded together without a joint, and in the luminous space the tanned sails of the barges drifting up with the tide seemed to stand still in red clusters of canvas sharply peaked, with gleams of varnished sprits. A haze rested on the low shores that ran out to sea in vanishing flatness. The air was dark above Gravesend, and farther back still seemed condensed into a mournful gloom, brooding motionless over the biggest, and the greatest, town on earth.

That's probably pertinent in some way.
