Cover Art of Sandman (1989) #4.
*Morpheus descends into Hell to recover his helmet. Challenging Lucifer himself, he wins the right to reclaim his helm, if he can detect which of a million demons possesses it. his sands identify the culprit: Choronzon, a duke of Hell, who demands they settle things with a contest. Each will conjure a powerful notion, which the next must vanquish with a mightier one. If Morpheus can invoke a truly unconquerable power, he recovers his property; if Choronzon wins, Dream serves in hell forever. Morpheus wins by invoking "hope," and escapes Hell with his prize... earning Lucifer's enmity for his pains. *Source: Back of card
