Issue #293 of Weird Tales (Winter 1988/89) was the special Avram Davidson issue, but in addition it featured a cover and interior art by Hank Jankus. It was a memorial issue, "another lament for a maker, ...gone from us, felled by a heart attack in mid-October." Some of his best work was in covers he did for Fantasy Review.
Going to Google and just searching on "Hank Jankus art" yields a treat for these eyes. But it may be even better to click the links to his work provided here: http://www.isfdb.org/cgi-bin/ea.cgi?2.... I really like this cover, the colors and lighting: http://www.philsp.com/data/images/a/a...
