Reset your password or make a new account - it'll be easier that way given thumbnails are currently dead (also I want to encourage as many people as possible to edit things). Case in point, I tried to guess which issue of EGM that was, and I chose #21. It's not 21. But 21 does have this: https://info.sonicretro.org/index.php?title=File:EGM_US_021.pdf&page=46 Scary thing is, I would have seen this when I added the scan. I think it's the introduction area, minus the goal blocks on the left. Presumably if you went out that gap, you'd fall into the void.
