Let's put some scans in
1) Tom answering to my own question that it is NOT canon
The story being mentioned non-canon on Marvel bio ( Instance # 1)
takes place in Earth 4321
Well later it says something similar happened in 616
Honestly a bloody cop out.
[ NOTE: THERE ARE LOTS AND LOTS OF EVIDENCE SAYING IT IS CANNON TOO... JUST NOT POSTING THAT AT THE MOMENT BUT THAT CAN BE POSTED AS WELL ]
