Morrow After Kirby

Having looked through the Perry Rhodan covers earlier, I didn't make this connection until I was rereading Fantastic Four from the beginning. This Jack Kirby panel is from FF 66 (Sept/67), the first half of the Citadel of Science story that culminated in the revealing of Him. Notice what Gray Morrow used and didn't use in the 1973 A World Gone Mad painting--he incorporated the technician into a shape in the tech.
