1. George Rozen's "The Creeping Death"
This has it all (
except for a girasol ring). The colors are great without being garish. The rendering is spot on. We have the single eye in the skull (creepy) and we have The Shadow as a shadow. The simplicity and the use of the spotlight just make this my favorite of the these covers.
2. G. Rozen's "The Book of Death"
All time classic that screams pulp and The Shadow Magazine. Can't argue with the rendering of this at all and for many I'm sure this would be #1.
3. Graves Gladney's "Voice of Death"
Again, the simplicity of the design, the use of The Shadow as a silhouette. The outline of the skull and the white glow make this a bit more graphic and puts this behind the other two, but the composition and punch in the face nature of the image make this an unforgettable cover.
4. G. Gladney's "The Scent of Death"
This used to rank higher for me and is still one of my favorites. I believe this (and I could be wrong) cover won an award of some kind. I'll try and do a bit of research to find out for sure and, if so, find out what the award was.
5. G. Gladney's "The Crimson Death"
Never really liked this cover for a variety of reasons. The Shadow just doesn't look right to me; the use of a rifle (although to be fair, it's probably in the story); the liquid pouring out doesn't feel authentic; and the tuft of hair is distracting. Of course, these are all just my opinions. Feel free to disagree.
