Even if I had a Wii U with NSMBU and NSLU, I bought this bundle.
I kept the game (NSMBU+NSLU) since I'm collecting every Mario games. I can scan the front and back of the boxart. The only problem is that I can't open the game box since I want to keep the game sealed for my collection.
Here's just a quick picture I made of the game:

By the way, I was wondering... Even if this is (will be) a rare game, it is comparable to the game Super Mario All-Stars + Super Mario World
and this version of Mario All-Stars is on the List of Mario games on the TMK website... NSMBU+NSLU is not. Why?
I think both of these games are comparable.
