I love this cover for Excalibur #6, drawn by Alan Davis, with Paul Neary inks. An 'Inferno' tie-in realeased March 1989. The five members of Excalibur in demonic form portrayed perfectly by Davis, exuding the fun that was contained within.
Fighting bad guys is serious business, and can sometimes be quite dark to read, with Excalibur I loved the fun elements, it's what made this comic so good, made it stand out from every other comic released, and combine that with Alan Davis' art, and it was a sure fire hit.
Every week I'd buy a stack of comics, and would always save the best ones until last, Excalibur was always the last comic I'd read.
