Let me set it down for you guys (and girls!). Of the four panels of the double-gatefold, three of them are penciled by John Romita Jr. and inked by Scott Hanna (the skyscraper signature says "JR JR + S.H."), and they connect to form a single image -- the front cover, the back cover, and the back gatefold. The front gatefold is penciled and inked by John Romita Sr. Here are the four panels, from samruby.com:
INSIDE BACK (John Romita Jr. and Scott Hanna)
BACK (John Romita Jr. and Scott Hanna)
FRONT (John Romita Jr. and Scott Hanna)
FRONT INSIDE (John Romita Sr.)
Hopefully that clears this up. As always, samruby.com lights the way! The page entry, by the way, is HERE
