And speaking of Rafael Grampa, I really dig this variant cover to American Vampire #6 :
"I tried to make a 'horror film' poster, but very pop! It is based on some dirty and rough grindhouse movies posters + punk rock cover albums," the artist said on Vertigo's Graphic Content blog. "I loved to do it! We, comic book artists, need to hold the same style for a whole project, so it was an incredible chance to experiment something different. Thanks everybody and hope you like it."
