Amazing Spider-Man Vol.1 #149
At Shea Stadium in Queens, the master plan of the Jackal finally comes together! On the infield grass, the Amazing Spider-Man fights to the finish against a carbon copy of himself - the Spider-Clone! With Ned Leeds in mortal danger, can the wondrous wall-crawler triumph over his clone and the Jackal too? But even if he wins, your friendly neighborhood Spider-Man may still lose Gwen once again. An emotional ending for all.
