Possible Springer pencils and Romita inks per Nick Caputo (September 2011), who originally only had Romita as pencil artist. Having viewed a large size scan of the cover, which is filled with repositioned and stated figures, it appears as though Romita redrew the Captain Marvel figure completely, as well as touching up other areas, with perhaps Springer pencilling and Sal Buscema inking the remainder.
The original indexer credited the pencils to Gil Kane and the inks to John Romita.
