I was going to post something along the lines as "Nice Cover, strange background", but after reading Satoshi Matrix's post, I have to agree.
As much as I would love to see a cover for the Japanese "Super Mario 2", it was not until Super Mario All-Stars when they called Super Mario Bros 2 JAP "The Lost Levels". Technically, if it is playable on the NES, then it's not quiet "lost" anymore, but found.
I think it would be great to have a cover for both "Super Mario Bros 2" and "Super Mario USA" covers as I too believe we were shafted out of a great game. Or atleast semicolons
Super Mario Bros.
Super Mario Bros. / Duck Hunt
Super Mario Bros. / Duck Hunt / World Class Track Meet
Super Mario Bros. 2: The Lost Levels
Super Mario Bros. 2: USA
Super Mario Bros. 3
Just a suggestion.
Another thing, and I know this is probably because this was so long ago, but strange background!

Just thinking about how well that would look in the collection of already completed and printed Mario collection
