Mystery Tales #8

A serious actor, portraying Hamlet, sees his star begin to lose some lustre when nepotism rears its head and the producer's cousin is made his understudy. The understudy proceeds to sabotage the actor to the point where he accidentally kills the actor's wife by mistake. Driven mad by his loss, the actor kills the understudy, finally giving him the perfect part to play, as we see his decapitated head being used as Yorick's skull in the play.
