That is a monster buck. But, the way they took the picture makes it look bigger than it is. Buck is out in front of hunter and head pointed out even farther toward camera. That along with them rolling the antlers forward and even closer to the camera has a big factor also. Hard to tell just how big that buck is the way they photographed it. The actual head and face of the buck looks like a younger buck to me but I could be wrong on that the way the face and head were rolled downward so the horns could get closer to the camera and make them look bigger.
