The Benes family
Ed Benes is one of the comic book industry's hottest talents, best known for his work on Birds of Prey and Justice League of America! Ed is currently penciling Batgirl while also training the next generation of comic book artists at the Ed Benes Studio.
Occasionally you will see a piece of Benes art come up on eBay, if not by Ed then by Mariah (his sister and an accomplished comic inker/embellisher) or Fred (relationship unknown).
There are not many Vampirella pieces by them, but what I have found are below.
