Not Really Marx, But...Mad Hatter and March Hare Bottle Stoppers

I didn't really know what to do with these, they are certainly not Marx, but are clearly made with Marx figures. These are bottle stoppers. They are made from some sort of metal, maybe pewter. They are the size of the SP figures, and are attached to a bottle stopper with a cork bottom for sealing a wine or liquor bottle.

Pretty cool, but bizarre. If they made these two, did they make all five of SP figures?
