Ahh, glad it was you that saw it then! I couldn't remember where I got that cover from. But, yes, I used the style from the only one I could find-- a Micro Machine cover. It was a nice layout, so I used that. I also used many elements from cover directly for this MM cover, instead of redoing that from my scans. All I did was clean up some lines and colors. Put a small shout-out above for it.
In a related note, I did a little cleanup to the Micro Machine cover above. If someone already downloaded it, probably should do it again. The front top line was rough. And Quattro Adventure is now readable when printed. Could be better, but close enough.
