The Fox promo art (Neil Vokes / Rick Burchett) Impact Line DC Comics

This art was produced to promote a new title "The Fox" for DC Comics as part of their Impact line in 1990. Measures 16" x 11" and was created on duo-shade chemical toning board.

Pencilled by Neil Vokes and inked by Rick Burchett. I purchased this piece from artist Don Secrease, who shared a studio with them during the time it was created.

My understanding is this appeared as an ad in DC Comics. I have never been able to locate it's use and would appreciate any help in finding where this might have been printed. Thank you!
