WildCat or Wild Cat Emblem / Nameplate

I recently pulled these from my late parents' attic. My first thought is that they look like they might have come from an old rollercoaster ride or something. I know there was a Buick Wildcat about 40 years ago, but these are much too heavy and large to have been auto nameplates.

Does anyone recognize them? I have searched for old WildCat rides quite a bit and can't find many pictures that show the emblems at all.

thanks,
