Some sources credit Joe Giella with the cover inking, including Green Lantern Annual, No 1, 1963 issue (DC, 1998 series) #[nn]. The cover is signed with a K over G, which at this time meant that Gil Kane did the inking also. The Schwartz pay records also list solely Gil Kane on this cover. Art Spotters Bob Bailey, Michael Evans, David Bachman and Gene Reed all agree that it is Gil Kane inks. Schwartz pay records provided by DC Comics.
