DirtyPair Biohazards collected edition unused cover

Acquired this piece from Adam Warren back in the 90's while at San Diego. While the style does really look like Warrens very early work I really remember him saying that it was Hernandez who did the art. This artwork is done on acetate. Kei & Yuri are coloured on the acetate while the other characters are coloured by the clear acetate being placed onto a watercolour background. This art was published (kind of) as an advertising solicitation in the back of some of Eclipse's books before the actual collected edition came out with a different cover.
