The Official Marvel Index to Marvel-Team Up featuring Spider-Man # 3-( wraparound cover- mechanical )-by Sandy Plunkett & P. Craig Russell

This is the mechanical make-ready by Sandy Plunkett & P.Craig Russell..a beautiful Spider-man & Killraven/ War of the Worlds cover, signed by both Sandy Plunkett & Jim Shooter....why did Jim Shooter sign it?...at the time he was EIC at Marvel and had to approve all covers before they went to the printers-( this is the art they printed from ).---( Sandy was always getting after me about inking with a pen, so he gave me this cover to inspire me...but he wanted me to use the brush more-thanks Sandy, for all your help and advice.)
