This is a no brainer. El Jefe offered a million bucks for this scoundrel's head. You can buy it on eBay for $1,500, HERE.
The head's description reads:
This Head was designed by the infamous John Chambers, who designed Planet Of The Apes, and many more. I'm Nico De Silva, the actor, in the picture title, Bring Me The Head Of Alfredo Garcia.. John Chambers made three others. This is the original and only one I know available. Its a collectors "must have" item. Sam Peckinpah also directed Classics such as; The Wild Bunch-Pat Garrett & Billy the Kid-The Gateway, and more more.This would be an amazing collectible to have on the shelf.
