I was born on March 5 1975 so I missed this by two months, Giant-Size X-Men came out in May of that year. Not much came out in March in 1975 for comics that I know of. Ha at least I’m older than Nightcrawler, Storm and Colossus by a few months. Those young whipper snappers!
There was a Spectacular Spider-Man issue I jacked from the library when I was little, but I decided to use this since Walt Simonsons run on Thor is one of my favorites to read and I am a huge Thor fan. Came out June 1986
