Super Mario Bros/Duckhunt/Track Meet variations?

[eighteighteenpm]

Was at a pawn shop today and I saw they had several Super Mario/Duckhunt/TrackMeet cartridges.....though on one of them the picture of Mario had him wearing his regular colored overalls, rather than is fireflower colors.  Can anybody verify this sort of variation, or could it be a fake/i'm insane?
