I am also now in search of this. I found photos of the box online but no scans. I made a placeholder cover with what I found just so I have something to put on my box. I can share that with you now. It's nowhere near perfect, like I said a placeholder. It's about as good as the cover for Magical Quest 2 on the site.
Hoping somebody finds scans soon and can improve covers for 2 and 3!
