Where to buy a tire cover like this one? Pic attached

[chrisntam]

I'm looking for a tire cover to place over the tire in the trunk so when I put stuff in the trunk, I don't have to worry about it getting dirty.  Here's a pic of something like what I'm looking for.  Maybe they were available for later model cars?  Late '70s?  Any idea where I can get one?  It would need to be for a full size spare...
