NFTA: The Amazing Spider-Man #14
I have no jokes for this one. It's the first appearance of what many consider to be Spider-Man's most iconic villain, and the one that has caused the webslinger to suffer the most... Other than the time Doc Ock killed Spidey, but that's besides the point, this is the first appearance of Green Goblin, in the pages of Amazing Spider-Man #14. by Stan Lee and Steve Ditko. Originally, the Green Goblin was supposed to be a weird sorta ancient creature that escaped and started attacking Spider-Man, but then it was changed to just a crazy guy in a costume. There is so much shit going on in this cover, Spidey is clinging to the top of a cave, while Green Goblin is about to touch Spidey's balls with his amazing flaming hand, and the Enforcers are cheering him on. You see that blue box with red borders? You see what it says? THE HULK is guest-starring in this issue, OH BOY! My 2nd favorite Marvel character! Watch out! He's about to punch the reader! Funny little tidbit of info...
