A jackalope is a well-known taxidermy gaff (a fake specimen). One is made by attaching any kind of antlers to a regular taxidermied rabbit. They are usually displayed as a head mount on a wall, but sometimes you can find a full-bodied one.
This is one of only a couple of gaffs that we’re interested in procuring. We like real animals better, but as this one is so infamous we would like to add one to our collection.
