The style of the figures in the foreground looks very Kirbyesque to me - especially the man's head (including the shading) plus his shirt and the slightly elongated and muscular left arm, which is gripping the girl around the waist. The overall composition of the image, especially the dynamism and flow of the foreground figures, also struck me straight away as being 'Jack Kirby'. The inking is by another hand, and quite possibly Alex Toth's hand. It is certainly both heavy and stylised enough to mask Kirby's input, especially in the detailing. What makes the image interesting to me is that it is an unusually torrid one for Jack Kirby at this period. And that may be one of the reasons why his input is masked by the inking and the page is attributed solely to another artist. I also know that Toth and Kirby were friends. I believe I am right in saying that it was Alex Toth who later recommended Mike Royer to Kirby as being a young inker with potential.
I think it is quite possible that the composition is essentially by Kirby, then inked and fleshed out by Alex Toth, and subsequently attributed to Toth alone.
