I found out that the buck in the original pics is no hoax. According to the Boone & Crockett website, it is for real.
Scott Yetman was guiding for Diamond Willow Outfitters last fall, and was rewarded by being allowed to go on a hunt of his own. This giant buck was the result, and is reported to be Scott's first deer ever! Reports are that it will score approximately 190 as a typical, but it has not yet been officially entered into the record books.
I thought it might be a hoax as well, but wanted to do some research prior to posting. I didn't want to put out any information that wasn't accurate.
As for the pictures. I've heard and read that some people will freeze a deer in a certain position prior to a photo shoot, because it makes the pictures turn out better. Certainly possible for these photos.
Maybe we shouldn't be so quick to judge.
