Monday, June 4 is the final day that those eligible can cast their votes for the industry awards.
The vote is open to comic creators, industry professionals and academics and all nominees in any category.
The shortlist was announced in April, with Mark Waid's Daredevil leading with nominations in six categories.
Archaia's graphic novel Jim Henson's Tale of Sand - based on an unproduced screenplay by Jerry Juhl and the late Muppets creator - received five nominations.
This year saw the controversial dropping of the 'Best New Series' category, with organisers claiming that there were insufficient contenders of suitable quality.
The 2012 Eisner Awards will be presented at San Diego Comic-Con International on July 13.
