Recycle Art – Pterodactyl My first ceiling sculpture, wow is this fun, talk about conversation piece. All of the parts used in this one of a kind sculpture are man made found objects. The head and tail are parts from a John Deer combine machine. The tail extension is a coal sifter from a furnace and the wings are welded elementary school desk chairs. I will custom install this for you, takes about four hours with an assistant any where you want it hung. Total price on my Pterodactyl including installation is $3,500.00 and its guaranteed to light up for the rest of your life.
