This sprite sheet includes Goombas, Koopa Troopas, Piranha Plants, and Hammer Bros (the map version) from id Software's SMB3 port to PC, which ended up being declined by Nintendo and then became Commander Keen. Since no download of the demo is available on the internet, video footage of the game was used as a reference instead.
Some of the tiles in the thumbnail are ripped by Black Squirrel.
