Like one of the posters in the other thread said, it is what I've heard called a Cactus Buck. I've seen one mounted before that was about 20" tall and a foot wide with a bunch of kickers.
From an article on a Cactus Buck killed last year:
A cactus buck is a deer that has a condition called cryptorchidism, which results in velvet remaining on antlers and continuing to grow throughout the year. The condition generally occurs to bucks that have irregular testicles or have incurred testicular damage, which impacts testosterone levels. Testosterone regulates antler growth and development.
