Ralph Reese's The Rats & The Roaches

Here's a couple of far-out fear fables from the mean streets of '70's New York, courtesy of Thomas M. Disch, Gerry Conway & Ralph Reese, and originally seen in The Haunt Of Horror and Monsters Unleashed respectively.
No one's better at desperate, pockmarked, pus-ridden and sweaty characters like Reese, and a couple of tales about the other denizens New Yorkers have to share their city with is tailor made for his superbly stinky stylings.
The Rats also has some fun cameos, with Roy Thomas & Trina Robbins as the young couple, and even Reese's mentor Wally Wood popping up in one panel.
But that's icing on a rotting cake. The real treat of both The Rats and The Roaches is the absolute, skin-crawling reality of it all.

Jesus Blasco At Marvel

No really. The Steel Claw's master of chirascuro, Jesus Blasco, really did do some stuff for the black & white Marvel mags back in The Bronze Age. Lifeboat! is from the 2nd issue of catch-all title Monsters Unleashed, while The Claws Of Tryphon comes to us via Vampire Tales #2.
Esteban Maroto also did a Satana strip as I recall, suggesting Stan & Roy initially attempted poaching all Jim Warren's Spanish stable off him, before settling in with thier regular team of artists.
Neither story is particularly groundbreaking, but who cares about that? Jesus Blasco could make a still life look like the moodiest, scariest thing ever.
Tryphon also comes with an unexplained handover to John Romita in the final four pages, which makes it doubly fascinating, watching Jazzy John trying to fit his style around Blasco's. He really was the go-to guy for eveything, wasn't he?
