[5] It was Elias's work on Black Cat, a stuntwoman turned crimefighter, for Harvey Comics, that stood out in this period.

The series was praised by comics historian Trina Robbins for its "logical" and "straightforward" approach,[6] in contrast to more fantasy-oriented titles like Wonder Woman.

Elias worked both as a penciler and an inker in this series, with an art style largely influenced by artists such as Milton Caniff and Noel Sickles.

Elias' work on comic strips included a two-year stint as an assistant to Al Capp on Li'l Abner.
