Below are adjusted scans of photocopies taken in the Kirby home of Jack Kirby’s pencil script and art containing the first appearance of Darkseid’s uncle, Steppenwolf. There he is in the first, upper left panel of page 2 of “The Pact!”, Kirby’s epic Fourth World/New Gods backstory published in New Gods #7. Steppenwolf attacks Izaya (a.k.a. High Father) and Avia in a moment of peace on New Genesis. Trouble ensues.
Note that Kirby originally numbered the fifth page in the sequence “7”
